Opens in a blank window
When installing release catapult-win-x64-24.11a it opens in a blank screen like so:
On Win 10
Try running catapult from cmd with a command like this catapult-win-x64-24.11a.exe -v > log.txt . That should create a log.txt file near your catapult exe with some potentially helpful debug info in it that you can post here.
Also you could try running older releases and seeing if they work to help pinpointing the issue.

This is from opening and then closing it. Old versions do work, as in the software works but the functionality isnt there because it cant fetch releases because iirc the git repo name changed for cdda or something? So works but not really.
Does renaming or moving catapult_settings.json do anything? It's in the same directory with the catapult executable.
POOOOG it worked, I guess because I installed it "over" an old version, so it maybe doesnt check that the settings file is from an old version or some such thingy? How did you figure this out if you can explain a bit so I learn something?
The log you posted had an error about not being able to open the "Grey.theme" resource file so I switched the launcher on my PC to that theme and then compared your log file to mine in WinMerge. The difference between the two logs was that my launcher was loading "Grey.res" successfully and yours was trying to load "Grey.theme" and failing. So apparently the naming convention for the themes changed in one of the updates.
