Can't repair corrupt Lightroom catalog

"corrupt catalog" may be part of a larger problem.  LRC seems to  ignore the fact that I open LRC by selecting a specific catalog.  LRC attempts to open the old original catalog, which it declares "corrupted."  I do not seen any sign of a "repair."

STOP

I am experiencing this issue with a catalog. Is it possible to get some help?

I need a catalog repaired as well. Can someone from Adobe pm me and help out?

I just updated to the new Lightroom Classic and it updated my catalog and now it says it is damaged and cannot repair it. Is there any way I can go back to before the update? Or can you all find a way to repair it?

I have the same issue - can someone help?

Hello! It appears as though people are sending their catalog to tech support in an attempt at recovery. Am I able to do this? I have also gotten the "cannot repair corrupt catalog" error.

No puedo abrir el programa

My catalog was working yesterday and is now corrupt. Lightroom does not succeed to repair it. What can I do?

Same problem. When booting Lightroom Classic it says it is corrupt and cannot be used or backed up. Then Lightroom says it had problems reading or writing from the disk attempting to repair. I uninstalled and reinstalled it, but that did not help.
