Folder count shows 0 - Catalogue corrupted

[Mrik]

Hi,
I'm very lost now with catalogue corruptions.
I have my entire collection of photos since 1980, around 2 TB that are on my HDD F:\.
My catalogue get corrupted and show a count of 0 photos in  nearly all folders are imported.

Catalogue, crashes, get repaired but still shows 0 photos.

I've restarted new catalogue importing 10-20 folders. It takes me ages...
Lets say that each time when i arrive aroud 80 000 photos in the catalogues it gets corrupted than shows 0 photo.
If i remove some folders with photo and add them back, they are added again.

After a corruption, catlogue shrinks from 80000+ to 9000 photos.
Sometimes i crashed around 80000 sometimes 120 000.

Plenty of discussions here in this forum about folders showing 0 photos and how to fix it

and others

No need (yet) to jump to the conclusion that the catalog is corrupted.

Lets say that each time when i arrive aroud 80 000 photos in the catalogues it gets corrupted than shows 0 photo

Let's not say that because it is not true.

In your Folders panel, scroll further down and see if you have any duplicate drives or folders.

No duplicates in the folder section was found.

So i restarted from scratch and created a new Catalogue.
Remove the xmp & face detaction in automatic mode from the library preferences.

It took me 24h hours to get the entire catalogue loaded again. 
Showing 121k photos...i was happy!!!!

And today i open it again... 25k photo some...randomy some folders are correct, some showing "0" some "..."

Before coming here to created this post, i parsed and tried a lot of the community suggestions.
Thanks @dj_paige & @GoldingD for you support!

Any other idea are welcome :), i'll try them!

Try loading a backup and see what happens.

I don't think you are opening the same catalog that last night had 121K photos. What happens if you use your operating system's search feature to find all files on all disks whose name ends with *.LRCAT, and then you open each one found? Do you find a catalog with 121K photos and no zeros?
