We are running SharePoint 2016, and up until now have had no problems with Business Data Catalogs. Now when I try to access a page that has a DBC webpart on it I get this error and the page won't load at all:
Server Error in '/' Application.
Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

I even tried to add a brand new BDC webpart to an existing page that has nothing on it, and when I click to insert the webpart I get this error:
"Index was outside the bounds of the array"
I reset the BDC service from Central Admin and no change. Like I said everything was working fine yesterday, any suggestions? Thanks.
