If a format and reload is not your cup of tea try 3.38.88 version of ICUE.
I could not get ICUE 4 to start with Windows 10 22H2.
I tried uninstalling reinstalling, deleting app data restarting running as admin not running as admin etc etc
Installed 3.38.88 and ICUE starts with Windows now.
However, I may bite the bullet at some point because Version 4 adds hardware level lighting control.
Meaning you can select the lighting effect for shutdown and restart when ICUE is not running.
For example all my fans turn red from restart to desktop when ICUE starts running again.
Certainly not a big deal but a nice to have for sure.
