A new release 2.93.641.0 came out today (5/12/2021) but does not address this issue. Same error. The version of Microsoft.Web.WebView2.Core on disk is still the same, and apparently whatever assembly needs it still wants an older version.
Here are the details:
Feedback Type: Frown (Error) Error Message: Could not load file or assembly 'Microsoft.Web.WebView2.Core, Version=1.0.664.37, Culture=neutral, PublicKeyToken=2a8ab48044d2601e' or one of its dependencies.
