Hi @anonymous9915,

Since you are using Windows, my quick educative guess would be this is something to do with line ending which windows just does not get right. Can you once run the example project and see if you can reproduce the same?

I can also reproduce this error if one user is on windows and another on osx, so it seems that line endings could be the cause of the error.

If you force the monaco editor to a specific line ending the error goes away.

editor.getModel().setEOL(0); // 0 is for line feed LF.

Yes, I did the same to fix.
But I don't know why these errors are still coming in production for many of our users irrespective of the operation system.
sharing some of the errors below ->
Assertion Failed: Retain expects a positive integer.
Validation Failed: Expected a Truth value
Invalid Operation Encountered: The Operation recieved was either Invalid or Corrupted, please retry!

The problem will persist if you have any stored models in firebase that have another EOL character than the one you set the monaco editor to use. You will have to migrate those stored models as well.
