P: LrC 12.2.1 fails to start/launch or is extremely slow launching.

I can not find it also.

On my computer there is no metrice.json file.  When I tried to open lightroom, it could not find my catalog.

And asked if I wanted to update.  I can open with an OLD catalog from 3 months ago, but I can not open lightroom with my backed up catalog from 3 days ago.  I can not open lightroom with any of the backed up catalogs.  WHEN ARE THEY FIXING THIS? 

When I tried to open Adobe Lightroom today, I got also a window that said: "catalog not found", when I clicked again to open Lightroom, there cam e a screen that said: "Update Catalog" I clicked on that but nothing seems to happen.  BUT LIGHTROOM DOES NOT OPEN AT ALL ANYMORE.  DID THE FIX BUT THERE IS NOTHING IN THE CACHE TO DELETE.

I can not start Lightroom.  I followed ALL the instructions, clicked on make the hidden files show in Windows 10.  After doing all that, C-users\username\app data\local\Adobe\lightroom\Caches\  THERE IS NO: metric.json.

What do I do NOW?  And why after 5 days is this not solved?

THIS IS COTING ME MONEY

@Kerry wilcox, "I don't have the metrics.json file!!!!!!! "

If you turned off usage reporting and restarted your computer right before checking for that file, as described above, but you're still experiencing bad symptoms, then you're likely suffering from another problem. I suggest you start a new thread, describe the symptoms in detail, and copy/paste the results of the menu command Help > System Info.

Lightroom Classic still opens, a little slower though...syncing barely works.

I don't have the metrics.json file!!!!!!!  I have the local.json but nothing that says metrics.json

I'm now having uses with Lightroom Classic.   Starts ok but get the spinning wheel that just doesn't stop.   I have uninstalled LRC and restalled it.  I have resetpreferences. 

Im on a Macbook Pro with M1 chip with no other programs except for PS all linked to my CC. 

All photos are on SSD drive so loads of memory and Ram. 

Not sure what to do now, please help
