Lightroom Classic freezes if AdHoc network has ever been enabled

Lightroom is unusable after enabling an AdHoc Wi-Fi network using this method:

... even with the AdHoc network off, Lightroom still freezes after a few minutes. Lightroom Classic 13.3 (and 13.2) will get the spinning beach ball of death and freeze for several minutes at a time. CPU usage rises and hovers around 100%.

Details:

M1 MacBook Pro 

16GB RAM

445GB free space

MacOS 14.5

Lightroom Classic 13.3

Sync Paused (off)

Empty Catalog

FWIW the AdHoc Wi-Fi network is needed to share shoots with clients on an iPad during tethered shooting with Capture One Pro. The AdHoc Wi-Fi network only affects Lightroom, not Photoshop, Capture One, Photo Mechanic, Microsft Word, Mail, Calendar, etc,. I suspect Lightoom is attempting to sync. Bug occurs with Sync on or off.

I've reset the computer three times, reinstalling all apps/settings. The only way to resuscitate Lightroom is to remove the AdHoc network with terminal command:

sudo networksetup -deletepppoeservice AdHoc lo0
