I just installed the latest version of Lightroom classsic and I've never had so many issues. The application keeps crashing and I can't do my work!. First I thought it was due to the developing mode as it first appeared blank and could not do anything there, then started crashing when using the quick dev module under grid mode. Each time I'm forced to log back into Creative Cloud and now the whole program just shuts down after 30sec of being open by itself.
For some reason all the little issues I had with each update were due to this creative cloud loging for one thing or another...Now I can log in fine each time but just keeps crashing.
Resetting the preferences is the first thing I tried without success, I was able to adjust the exposure on one image before crashing but that was about it. I will try a full restart as you recommend and hope for the best. I will report back to see if this is a fix for anyone that is having a similar issue.
