From another thread it appears that this issue requires that you have done a surprise trade before

So the solution is to do one of the following: do a surprise trade, use an old PKHeX version for now, or use the PKHeX development build if you need a change that only exists in the latest release

 

I haven't done suprise trade on either file so i'll try that and see if anything changes, but I had the same problem on the pkhex development build after i put the plugin folder in the same place as it, only with tera-finder in the folder, so that's definitely the issue i'm having at least, after suprise trade i'll update this

I'm having the same issue, happens with both Scarlet and Violet save files. I read the error and it mentioned tera-finder, deleted that and it's working now. reinstalled the plugin and got the same issue again with the same file i just had opened, so I think the latest tera-finder is the issue with this build of PKhex
