LrC stops abruptly

Explorer ,
Oct 03, 2025 Oct 03, 2025

HELP!
Sometimes LrC closes without warning. Other times i get an error box saying a problem reading the catalog and then closes, others that I can report what I was doing which could be scrolling through my files in the library or develop mode, searching, syncing, and other thing too.
this has been a problem for months. I have been traveling with little access to a robust inernet connection and made a new catalog that i have been using for new files. 
I have kept my Adobe apps up to date. Lrc 14.5.1 currently.
windows 11 up to date.
Sometimes i will delete the left behind on sudden crash files and other times i just restart Lrc without deleting them. When it does a catalog check as it has on dozens of crashes the program has only done a catalog repair 5 times i believe which has not made a difference. Even after a catalog check it may not start again right away.
I have deleted and resynced Lightroom cloud which has somewhere around 40,000 images from my phone/s that are now in one synced folder.
I have unsynced all my Collections and resynced only 4
I have deleted and let rebuild previews. 
I have made a new catalog and imported my old catalog.
I had over 450K files in my catalog. 
i deleted many folders from LrC without deleting the images from my hard drive. 

I now have under 350K files in LrC.
I have always converted my files to DNG on import. 
I turned off auto save changes to the file. 
Now Ctl-S crashes LrC

My catalog and LrC program is on my boot drive, an M2 4TB SSD.
the back ups go on a seperate M2 4TB SSD
i also have 2 1 TB internal drives and two 14 TB and 1 8TB HDD, all internal that have files on them. none are near full.
128GB of Ram
