On prem EAC shows in text only on Exchange 2016 after CU20 and KB5001779 install

Copper Contributor

Last night I upgraded my Exchange 2016 server from CU18 to CU20 and installed KB5001779.  Now I am no longer able to load EAC properly.  It just shows text like below.  None of the links are clickable.
