Startup Error

[HGPOfficial]

I got PKHex installed and used it a couple times maybe like a week ago and it was working perfectly fine. Turned on my PC tonight to update some things I didn't want to have to grind hours for and got this error whenever I tried to open the program. Tried reinstalling it and turning my PC off to no effect. Any help is much appreciated.

For whatever reason reinstalling/repairing dotnet somewhat fixes it. But trying to import a legends Z-A save file breaks it again, doesn't matter what save file it is.

Edit: Scratch that. It worked for like half a second and now it's back to the same errors.

I think it's because the game updated and now pkhex can't read the save file. Mainly because of the SaveRevision section in the error. But I could definitely be wrong.
