It seems that Windows insiders experience a problem after installing update build 21292.1010 (KB4601937).
The x64 emulation on ARM PCs won’t work anymore. Microsoft said this problem will be fixed if you uninstall update KB4601937. The problem should then be solved and everything should work properly again.
