Same problem on Mac mini M2 Pro
It’s better to reply as a reply, rather than in the comments; see Quinn’s Top Ten DevForums Tips for this and other titbits.

Thanks for that.
You only just filed this bug, so I’ve no news to share yet.
It looks like the CodeWeavers’ folks did a bunch of research into this. Do you know if they filed a bug about it?

CodeWeavers already had an open bug for OverWatch 2, that same bug also affects Diablo2:Resurrected
I‘m also aware of another Rosetta2 bug they have open that affects legacy WoW clients.
Do you have FBnnn numbers for any of those?

That would be FB15880492
I this now also affects Diablo 4 Test Realm/ that version might now be live with the Diablo 30th anniversary updates landing for both Diablo 4 & Diablo 2
I was just informed that FB21763885 might be more detailed and more easily reproducible.
