I'm starting from Windows 11 23H2, up to date, on my i9 iMac, 32GB memory, plenty of disk space. I've tried to apply 24H2 several times and after the update applies and the VM reboots, I get a blue screen asking for my keyboard locale that's basically showing the update failed.
I have the exact same issue. I have tried to upgrade several times and get the same result: Blue screen asking for keyboard locale. Answer "US". Result is failure to launch.
