Dynamo 2.0 open script and Strings only

Every time I try and open a dynamo script that I made only strings appear or the script crashes. It was just working. Has this happened to anyone else any suggestions.

Are you opening the file in manual execution mode?

Yes.

This is usually do to a conflicting add-in. Often it’s PyRevit but it happens with others. Try disabling that add-in and see if it solves the problem.

do you have any notifications in the dynamo menu or errors in the console?
what addins do you have installed?
can you open the file ok in dynamo sandbox?
