Safe mode temporarily stopped the issue with the external monitor disconnecting and then kernel panicking when it was reconnected - although the mouse freezing persisted throughout.
After 24 hours I booted back into normal mode and both issues returned.
The final step is to reinstall MacOS.
I object to spending my time troubleshooting their (probably) faulty product.
However, it sounds like reinstalling MacOS doesn't take a tonne of time.
If that doesn't work then I am firmly demanding a fresh machine.
And at least - having completed troubleshooting steps - I can throw my weight around in-store.
Fortunately, I immediately ordered both a Macbook M1 and a Google Pixelbook Go when my last Macbook died mid-project, in December.
It was so unpleasant having to find and rent a Macbook in Lisbon at zero notice so I could hit my deadline that I swore I'll always have two machines, no matter what I am in the world.
I later wondered if having a backup machine was overkill.
But it's nice to know I can hand the M1 over and continue working on the (pretty awesome) Pixelbook Go.
