You might want to check #174 for a solution. Try running export QT_DEBUG_PLUGINS=1 to see what exactly is missing

#148 is related as well

I couldn't find the issue by looking at the log as well. This issue is also common with other projects that use qt6. Try a solution from here:

[korcankaraokcu]

Installation script has been updated, try to reinstall from scratch. Do not use sudo while installing or launching the program, the scripts will handle it for you

[korcankaraokcu]

Thanks for the confirmation, closing the issue
