Macbook Pro freezes when external display connected by thunderbolt 4

As per the title. Random freezing (e.g. during scrolling on a website). This is generally temporary. Can be unfrozen by disconnecting the external display. There is another thread here somewhere that went stale due to no responses from Apple despite many "I got the same problem" responses.

External Display:

LG Ultrafine

Macbook:

2021 16 inch M1 MacBook Pro

OS X 12.4

64 GB RAM

MacBook Pro 16″, macOS 11.6

Update. Now the machine rebooted suddenly during one of the described freezing events. This needs to be addressed.
