Yep, that’s it basically.
Tried switching it from Swedish to French and that worked fine, same with Chinese.
When I switched from Chinese to English it launched weirdly enough…
I saved a copy of the picard.ini file when it crashed, tried renaming it back and sure enough it crashes/doesn’t launch.
Here is the ini i got when switching to english the first time and it started crashing: https://pastebin.com/EWn9VMWE
If you use this ini file it should crash.
I tried to reproduce that ini by uninstalling, removing all musicbrainz folders and reinstalling but I couldn’t do it again…
Guess it works now, can’t make it crash without using that ini that I saved.
I’m on swedish Windows 10 Pro 64bit. version 1809 (os-version 17763.253)
