Suddenly getting runtime error 236 with Delphi 10.

Suddenly getting runtime error 236 with Delphi 10.1 on start up (happens right after a component loaded shows in the splash screen). Seemed to happen after I added a component to Delphi 10.2. Help. I can't use 10.2 yet as waiting on a set of components to be ported to it (Instrument lab)
