Research direction

Start with grammars/MagicPython.tmLanguage and reproduce the loading error in Sublime Text 4 on the reported environment. Trace the invalid regex construct shown in the error and confirm that the grammar loads and Python syntax highlighting works afterward.

Written by the indexing model from the issue text.

Description

Editor name and version:
SublimeText4: 4121
Platform:
Ubuntu 20.10
Color scheme:
any: monokau, matherialUi, MaterialUiImproved
MagicPython version:
1.1.1
A sreenshot:
5-10 lines of surrounding code:
The error:

error: Error loading syntax file "Packages/MagicPython/grammars/MagicPython.tmLanguage": Error in regex: target of repeat operator is invalid in regex (?x)
  (.+?)
    (
      (?# .* and .*? in multi-line match need special handling of
        newlines otherwise SublimeText and Atom will match slightly
        differently.

        The guard

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

Syntax is not highlighted((
