You clicked on Random AVs and it gave it random AVs. There isn't a problem with that, because you can use candies to raise stats above the minimum values. If you don't want candies, then use the shortcut key for minimum AVs.

It says "Select Folder". There are no folders inside the folder you're in. Select a folder, press the button.

No, use the shortcuts.

No, because the ROM updates the abilities. Change the ROM to stop changing abilities (nobody has done this before, so you're likely not going to either), or edit the ability in the save file editor after it evolves. PKHeX is a save file editor. It cannot bypass game behaviors that update data.

Incorrect save size. Needs to be 128KB (0x20000 bytes), not whatever you have it exporting as. Trim it down in a hex editor and it works fine.

PKHeX is correcting your mistake; eggs do not have a nickname besides "Egg" (localized). If you would like to disable this feature, change the setting the [SlotWrite] SetUpdatePKM boolean to false via the program settings (Options->Settings).

Mass outbreaks: sure, if you modify the correct block. Which block is the correct block? Nobody has identified which blocks are responsible for mass outbreaks, or what is needed to be changed in each to get specific results. The block editor can do savefile diffs to let you know what changed between save files, so that will help narrow down the list to identify which is responsible. Remember that the save file changes can't make the game behave differently (like spawning unavailable species in the wild); that requires editing the ROM. How likely a shiny would appear: no, outside of giving yourself a Shiny Charm. Changing the amount of shiny rolls the game does is a game-code change, not a savefile change. Use a cheat code to change the game code while the game is running: https://gbatemp.net/threads/pokemon-scarlet-violet-cheat-database.621563/

Encounter-only Marks (like Weather and time of day) can only be obtained on wild encounters, not gifts or static encounters like raids. Use the encounter database to pick a template that will be compatible with whatever end result you want to have.

It exposes the raw savedata for research (before/after diff), and allows direct/indirect modifications for everything about the save file even if it is undocumented. SWSH/PLA/SV save files are stored as a collection of savedata objects (uniquely identified by a 32bit FNV-hash key), and each object has embedded metadata about the object (shown in the block detail list label). The dropdown allows you to select any savedata block object; the program will show the 32-bit key if it does not have a name assigned (manually identified and hardcoded by PKHeX's maintainers). If a block is a recognized object, you can see properties on the right side to change as you see fit. Otherwise, it will show the raw data similar to a hex editor, which you can export and modify yourself, and import when finished via the buttons on the left. There are some things that PKHeX doesn't edit, like fashion or importing past distribution raid data. But you can import these blocks via this interface.

Exports just fine.

Switching boxes changes the "Current Box" value for the save file. After which, the save file is "modified", not un-tampered. The program doesn't track every mutation to the save data to check if it was edited, so you should only really be checking immediately after opening the save file.

pkNX edits a folder that contains a ROM dump. Any files that are changed from the ROM dump are stored in the ROM dump's folder, inside a 16-digit folder (ROM's Title ID). This Title ID folder is what you copy to your console, and the console's layeredfs feature will load the files from that folder instead of the cart/SD when requested by the game. When loading files to edit, pkNX checks the Title ID folder to see if the file has been edited. If it exists, it loads it, otherwise, it reads it from the unmodified romfs. When you wish to revert modifications completely, you go into the Title ID folder and delete the modded files, so that pkNX loads from the unmodified romfs. When the files are deleted, the modded files will be gone, and you should be seeing unmodified data in-game and in the editor. If you are seeing randomized data in a fresh ROM dump, then you either didn't open the correct ROM dump folder, or you pirated a pre-modded ROM. Neither of which are issues with pkNX. pkNX does not load data that does not exist. It is up to you to ensure you are copying files and managing mods correctly; pkNX is just a program that loads data from where it is told to load from, same as the console.

PKHeX does not support ROM Hacks that modify the save file structure, or change things significantly from the base game.

Delete the layered FS folders on both your console and pkNX's local folder.

Yes.

It's in the tutorials and guide. Randomization of PID is a single command.

Depends. Things like exclusive tutor and level up moves that require the Pokemon to level up / evolve will require a higher level prior to transfer. Same for Gen1/2. Can always brute force the lowest possible value yourself.

There are 4 markings for early formats and 6 markings in more recent games. Keep looking.

Refer to the batch editor guides on how to find property names that you can use. All 6 that you listed are not in the list of properties. There's one property that starts with Mark***** that should be obvious how to set.

G-Max moves are not storable moves, see the Bulbapedia link. Entirely separate handling by the game.

Z-Moves and Dynamax Moves are hidden from the legal move list dropdowns as they are not valid out-of-battle moves to know. Google is your friend: https://bulbapedia.bulbagarden.net/wiki/List_of_moves

The entity db setting for Use Tabs as Criteria can be turned off, or you can pick a random nature in the editor then view the template.

Pokewalker PIDs are deterministic. Gender Ratio+Nature+TID/SID => PID. They're always going to be the same if the inputs (above) are the same.
