Answer 1

I had this issue when including two composer autoloaders from two directories where one originated as a copy of the other one (don't ask me why).

Based on this GitHub Issue I concluded my solution:

Delete the composer lock-file (e.g. composer.lock) and execute composer update.

In my case I just deleted the vendor-directory too.
