My MacBook Pro 2021 Apple M1 Pro is running Sonoma 14.1 and when I have it connected to my TV by HDMI it often crashes, the audio continues on playing as normal but the picture freezes and the keyboard is unresponsive. I have to do a hard shutdown to bring it back to life. Any ideas why?

I bought a Thunderbolt mini dock and its completely sorted the problem. And i now even have 2 monitors connected. So both monitor HDMIs go to the mini dock and thunderbolt USB C to Macbook Pro. I think its some issue with HDMI going direct to the Mac and it crashing the Mac, and getting panic alerts etc. Been using it like this for weeks now and no more problems at all.
Apple repair centre said i needed a replacement motherboard for about €800-1000 (even though no faults found with their diagnostics). Instead €100 on the mini dock has solved the issue
This is an extremely helpful reply, I appreciate the suggestions and will look into the cables and docking hardware. Thanks!
I am having the same issue when I'm connecting my macbook with HDMI through usb-c + bluetooth connected.

This. I have the exactly same issue, don't know what is the problem.
It happens to me when I’m using my trackpad. Which is the same cursor ! So maybe not Bluetooth related, and maybe cursor related ?
Tried this and - to my knowledge - most other output settings; the Macbook Pro still freezes.
This problem is happening on all MacBook Pro M1.
Thanks - as noted, CalDigit is already my in-office solution, so I'll buy the road version as well. Thanks for the tip - and shame on Apple for making this a necessity!
If you are having trouble with a Bluetooth mouse, it could be time to change the battery on that mouse. The computer may be registering fluctuations in the availability of the mouse and not knowing what to do about it.
