Anyone seen Group Policy Client login failed - access denied errors on win2016 VDA's running 1912CU2 VDA ? Its a random issue that doesnt impact all users and a profile reset or restoring the NTuser.dat from previous versions fixes the issues. Its exactly the same as this post https://discussions.citrix.com/topic/407739-upm-failed-to-copy-ntuserpol-to-the-userstore/ (i see same errors in the UPM log)
