Adding terms to Multiterm from within Studio 2019 no longer works

After adding some addons to Studio 2019, I can no longer add terms to MultiTerm from within Studio. I get the error message: "Unhandled exception. Error info saved to errorLog.txt file. Error message: 'Sdl.MultiTerm.Client.CppBridge.dll or one of its dependencies. The specified module could not be found.'"

How can this be rectified?
