I just upgraded viewer and hosts to 7.1.0.0. I am finding the almost every attempt to establish the updated Terminal mode crashes, both CMD and PS attempts, and in both contexts. Every great once in a while the connection makes ok. I would say it is about 98% of the time a fail. The Terminal windows tries opens then immediate closes out with a crash. No error messages appear. I have attached a log for your inspection. This is Viewer on Windows 11. Viewer on Windows 10 seems to work just fine.
