Same issue here. I updated and left my machine for a few days. Came back and was unresponsive. I had to use the 26.3.1 firmware and DFU restore. I have a 16" M2 Macbook.
I haven't had anything interesting to post over time, but glad I bought my domain years ago for various reasons (yikes, 2007 it looks like, 20 years?!). Will try to throw a PR up, young kids keep me busy.
