New 13.3 LR update does NOT start up on folder / image I last used.

[JanM33]

I've opened and closed my new LR update 13.3 for several days now and it does NOT open where I left off - always starts up on where it was I guess when I ran the update and updated the catalog. Windows 11 Home, v. 22631.3593. LR has always started up where I left off. This would classify as a bug in my mind.

My LR 13.3 remembers the last selected image for each catalog. 

First, restart your computer. If the problem persists, try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.
