TagStudio Version

Alpha v9.5.6

Operating System & Version

Windows 11

Description

Just downloaded portable version, tested out, changed language to Russian, closed the app
Now, when I try to launch it, it goes background. The process is present in task manager and loads both my CPU and RAM, but no GUI is visible

Expected Behavior

It should open like the first time?

Steps to Reproduce

1. Launch portable
2. Change language to Russian
3. Close and try to open the app

Logs

If only I knew where to find logs... or settings file
But I have a screenshot

Just found settings.toml under %appdata%/tagstudio. Changing language to EN reverts the issue

[zenelone]

For some reason setting ES produces the same issue
But FR works fine
Gotta just stop my investigation here

Tagstudio gets stuck initialising the MainMenuBar, specifically at the end of setup_file_menu with a call to 'assign_mnemonics' which results in an infinite loop.
Commenting out the call to assign_mnemonics causes the program to load fine.

Investigating into why it gets stuck in an infinite loop its obvious to see what has happened. When taking over from a weaker weighted action the mnemonic marker is never removed from the label (or it shouldntve been there to begin with) which causes the infinite loop. removing the mnemonic marker when overtaking fixes the issue of tagstudio not opening. i'll test more and submit a pr with the fix

[Computerdores]

The bug specifically happens when two actions in the same menu have a conflicting hardcoded mnemonic (which is invalid anyway and should not happen in the first place)
