V3: NLP could not launch and LrC froze up

A strange issue developed last night.

When I tried to launch NLP, LrC froze up and NLP menu didn’t show up. I even couldn’t exit LrC in the normal way. I need to shut down LrC in Windows Task Manager.

I then uninstalled LrC (keeping Lightroom Classic preferences) and then reinstalled. To my surprise, NLP was automatically installed together with LrC. However, the issue persists.

I have also tried reinstalling NLP again, but still no luck.

Should I try uninstall LrC without keeping Lightroom Classic preferences? Would I lose my existing Catalog?

Are there any other suggestions to reset NLP/LrC?

Found a solution from this thread:

It works!
