Tagging, collections, loupe display issues all failing to work randomly in recent lightroom upgrades

Massively frustrating having to restrict myself to older versions of LR classic as I have no confidence in the recent upgrades. Upgraded to 14.2 when it came out hoping it would be stable, but no the same issues

Have followed tips here previously of deleting "helper" file, no luck there. Have reinstalled old/new versions, no luck.

I've used Lightroom since before it was Lightroom. If I'm missing something I'd love to know. 

Bug info

1. LR classic 14.2

2. Mac os 15.4.1

3. Image in library won't display tag/star rating/colour

3. Can't create collection/smart collection

3. Can't rename collection

3.  No loupe info displayed

4. These are basic functions that don't work, ie the actual result means I can't do anything above.

Thanks for your help. I use LR to process clients images so this becoming increasingly inefficient and frustrating in meeting their needs promptly.
