Catalog corrupt- Any way to repair it?

My LR CC catalog is corrupt and I have no idea how to replace it.  I'm using a Macbook Pro (OS Ventura 13.4)  and LR version 14.3.

I was transferring photos from an external hard drive back onto the internal hard drive, but LR crashed as there was not enough space on the internal SSD.  I had to force quit LR as nothing was responding.  Then, when I deleted items off the SSD and tried to open the LR catalog again, it gave me these messages:

**The Lightroom catalog "Lightroom Catalog-v130-3" is corrupt and cannot be used or backed up until it is repaired.**. Then when I clicked on "Repair Catalog" another message appeared that read:

*Lightroom encoutered problems reading or writing from the disk when attempting to repair (the catalog).**  I tested the integrity of the catalog, but it immediately returned saying there was an error.  It did not provide any suggestions on how to repair it. 

I took these steps:

1. I used the disk utility function, but all was working well as far as I could tell.

2. Opened a backup catalog (a year old), which opened but mulitple photos were missing for some reason. If I need to rever to it I'm going to lose a lot of work, which I wolud rather avoid.

Does anyone have any ideas how to repair the corrupt catalog?
