Lightroom Classic hangs until Task Manager is opened

I have an extremely odd situation. Sometimes when I open Lightroom Classic, it hangs and Windows will put (Not Responding) in the title bar. It will stay like this until I open up the Windows Task Manager to see what's happening. Nearly immediately after opening Task Manager, Lightroom will continue loading and start working normally again. It is almost as if opening Task Manager reminds Lightroom that it is supposed to be loading.

In Task Manager, nothing unusual seems to be happening. My system load overall is low. There are no weird tasks running that I can see. While Lightroom is frozen, it is using minimal CPU. It appears to be idle. 

This does not happen consistently, but it is frequent. I see it about 3 times out of 5 that I start up Lightroom.  

I have tried different things, including relocating my catalog to a new SSD, creating a new catalog and importing all of my photos and videos into the new catalog. It doesn't matter if I've freshly rebooted the computer or if it has been running for days. The issue still happens with the same frequency.

I have tested to see if just waiting will make Lightroom Classic unfreeze on its own. It doesn't. I have waited as long as 30 minutes and it remains frozen until I open up Task Manager, at which point it continues loading and operates normally.

I am running the latest Lightroom Classic 10.2. This issue has been occuring for the last 2 or 3 months.

Has anyone else experienced this?
