After the upgrade from W11 22000.51 to W11 22000.65 almost none of our x64 applications work anymore. Event viewer shows ntdll faulting module. With version 22000.51 most apps worked. some problems with .net and multithreading.
Running W11 on arm on Parallels on MAC. It was W10 and it told me it could not upgrade because of TMP2, which is currently not supported in Parallels yet but 2 days later the upgrade from 10 to 11 was a fact, so I run with it
