Hey great to hear this issue is being looked into - I was about to post about the same thing on my end.
In my case I am using the same Win10 Pro x64 May 2020 - also latest EX100 but unlike tejas0007 - I use a bench system to test ISO on in real-time (just how I prefer) instead of VM in regards to potential issues as icy had mentioned.
Several instances of a full install fail. So I tried an edit session omitting anything to trigger errors to backtrack - such as with no integrations, no NET3.5, no driver removals, and also left out ISO/boot cleanup options- only component removal & tweaks....but still always the same outcome.
Image files load as usual at first but after that initial reboot will not go further to finish install. Get locked out with the blue error screen - NLS Data missing or corrupt - think its code 0xc0000225. Something "uncool" there on booting back into install or post boot.
I re-checked my USB drive/and system SSD and all works good with other previous images - and the original Win10 ISO still installs correctly - so beats me.
Anyway - that sums it up for me
Meanwhile looking forward to any solution(s) on the matter as it is being investigated tho.
Everyone hang in there and take care!
