Was this exact freeze happening already before?
It’s hard to say if this was the exact freeze - as it was freezing on very basic boards, often after switching boards. But I found the above is a good way to invoke a freeze on the box, and it will happen randomly, so it might work a bunch of times and then suddenly freeze without warning. If I can obtain any more info that would help I’d be happy to do so. The freezing is the only issue that I’ve discovered so far with the dwarf - otherwise the other functions work exactly as I’d hope/expect.
Hmm let’s wait for the new RC and after you try it let us know if this is still happening.
