      (?# .* and .*? in multi-line match need special handling of

Since the regex is very common in the tmlanguage I'm confused in ways to solve this...

@Levitanus check my pull request for the fix.

Please post an issue to the upstream, I believe this is a bug in SublimeText 4 since I've seen this error in other packages as well.
