Installed - tested and working fine. Thank You Microsoft.
Maybe you could re-release the 1909 enablement package that broke it too. :)
I notice file search problems, but do not use that function to much and don't care to find a fix, but after the 1909 update I was having very big problems using explorer through office automation (GetOpenFileNameA API) which need nearly three minutes to find any file in a folder...
Now, after the update you say, everything seems to work right again.
Thank you, Jon_Feth, for posting it and thank you, Microsoft, for solving. That one was really a big issue....
