Additional comments

This happens when plugin:@typescript-eslint/recommended-requiring-type-checking is enabled

I think this can be worked around by changing the name of the variable after :then

Thank you for posting this issue.
Using the same name for #await and :then does not seem to work. To fix the problem we need to fix the parser.
