Please don’t top post, it makes it difficult to follow the thread.
Insert your replies inline the previous message. Thanks.

Does the app work ok apart from not being able to run a particular
migration?

Do other apps work ok?

Can you post the files Gemfile and Gemfile.lock

Also what happens when you run
bundle update mysql2
as suggested by others (post the output of the update command here).
