[Windows] Firo Qt starts, shows splash screen, then closes

[justanwar]

After upgrading to v0.14.13.3, some users reported that their Firo Qt wallet starts up, shows the splash screen, and then closes.

Nothing was written to debug.log.

In Registry, Computer\HKEY_CURRENT_USER\SOFTWARE\Firo\Firo-Qt exists and strDataDir value is pointing to the correct datadir.

Other information

OS: Windows 10, Windows 11

User 1 was running at a display resolution of 1024x768. User 2 was running at an unknown resolution, but reported that the create new wallet window was drawn larger than could be displayed.

Workarounds

1. Start firo-qt.exe with -resetguisettings flag. A window will pop up asking the user to specify the datadir, and for most users selecting the default option allows for a normal startup of firo-qt.
2. [Does not work] Start firo-qt.exe with -datadir flag pointing towards the correct datadir.
