I briefly get the CCP logo splashscreen followed by nothing. The evelauncher process appears for a second or 2 then disappears.
I checked the logfile with loglite (found it in the EVE folder) but I don’t even know how much that says about anything. Either way, there were no apparent errors.
Will I lose my settings if I reinstall everything? I hope not cause I already had to redo most of it when the update broke part of the UI not so long ago.
Edit: Fixed by deleting cache on 2 locations found here: https://support.eveonline.com/hc/en-us/articles/5887708213276-Launcher-does-not-start
