Cannot run any IW app after update to 15.6.1

[PDSBILL]

Installed ver 15.6.1 in Delphi 11 update 1.  No issues installing and latest License expires 2025
Upgraded from 15.2
When I try and compile a simple iw standalone app with just a blank form i get the following error

[dcc64 Fatal Error] IwtestPC.dpr(12): F2084 Internal Error: URW8036

error appears in uses IWappForm

Any suggestions.
