I have done everything I could find on this server about this topic but keep getting that message.
So I have placed the WASM module both from the MFC and manually in the community folder but nothing helps. In 2020 it works correctly.
However, after a long search I discovered that in the MSFS Developers mode > Packages the State of the mobiflight-event-module is set to "SystemDisabled" and saw an image somewhere on GitHub where it is set to "Registered".
Maybe it should be set to Registered for me too? Could this be the cause? And any idea how I can solve this?
