out of no where unity is taking 45 minutes to start. The splash screen is just sitting here for over a half hour.
CPU says 07% being used and memory is 23%. I cannot figure out why its slow slow. Everything else is blazing fast on my system.
Something Changed in the File Dictonary?
have you something imported a big mesh or something?
generally you should always give more information what you have done, what system do you use and what version (lizenz, release, patchlevel) of unity you use.
Are you sure it hasn’t just crashed? Also, just open the editor log and have a look, it’ll tell you exactly what it’s doing or not doing.
