There are several similar issues on the al GitHub but from my investigation the problem is wit AL Object Designer extension.

Getting the same very often when looking up functions in standard applications my app has dependency on.

This always happen if you open .dal files. .al files work without any problem.

@dennisroczek then why sometimes it works perfectly and without errors, sometimes gives an error. I could not find dependency on what I do and how it performs...
