Lightroom disconnects from network after 5 seconds

[sheilafaye]

Lightroom has been consistently disconnecting from the network, after running for about 5 seconds. I've restarted computer, re-installed Lightroom, gone back to previous versions, troubleshot my network (no issues there, running strong), turned off firewall, moved the library location, turned off the graphics processor. 

I'm unable to export any photos and since I'm a photographer and shoot in raw, this is critical. The message I get when trying to export is: 
"Some images could not be exported at the size you requested because we couldn't access the full size original."
"Your computer is offline, going online will allow you to download files." 

My computer is not offline, and I've spent the last two days trying everything. Any help would be greatly appreciated. 

Running Adobe Photoshop Lightroom version. 5.3 on MacOS Montery version 12.3.1

This may be a security setting problem rather than a network problem. Apple changed the security requirements in MacOS Monterey. Go to MacOS 'System Settings - Security & Privacy' and add Lightroom to "Full Disk Access". Click on the lock icon to unlock the settings, then click on the plus icon to add Lightroom if it isn't already listed. If it is listed, then just enable the checkbox.

Lightroom has full disk accesss. Still does not connect.

Is there anything else anyone could suggest? I can't get anything done until the issue is resolved.
