Lightroom Classic: folders/photos go "missing" after renaming them

Hello,

I always import photos into a yyyy/mm/dd based folder structure, and then rename the day-based folder to be a little more descriptive -- for example, "2021/04/04 Beach", or something.

New in version 10.2, the renamed folder and the photos within it go "missing" (dark grey icon with question mark on the folder) when I do that. I need to navigate to a different folder and then return to the folder I just renamed and then it will recover -- at least most of the time.

The photos inside the folder do remain marked as "missing" even after that though. When I quit and restart Lightroom Classic, everything is instantly back "online".

Is anyone else experiencing this problem?
