Lightroom CC stuck Syncing

I have found numurous topics regarding this issue but none none of the suggested solutions seemed to have helped so here is my problem:

Running Lightroom CC across 4 devices; 2 mobile, 1 MacOS and 1 Windows 10 device.

• 1 of the mobile devices (Ipad Updated to ipadOS 15.0.1) is stuck "Uploading 1 photo", when filtering for this photo none of them can be found.
• macbook Pro 13" early 2015 running MacOS Big Sur 11.6, Lightroom stuck "syncing 4 photos" same thing as above, when trying to filter the photos none of them can be found.
• Windows Laptop Running Windows 10. Stuck Syncing photos, no amount is displayed.

Emptying my catalog is not possible at the moment as there are about 5000 photos in them which I am filtering out at the moment some with edits some without edits.

The option/shift Start Lightroom didn't work and I couldn't find the suggested sync files in the Libraries.

Hope to hear from anyone who knows what to do about this?
