Huh, Ghidra has a weird concept of project ownership. I can't edit the project I have in my Nextcloud from a different machine using a different username because... that's not the owner? Literally no other program I know has this weird behavior o.o
It seems there isn't even a good solution other than setting up a dedicated Ghidra server?
Maybe I can write a script that renames the owner in the project file to the current one automatically but that is so ass backwards lol
