            whole_line = self.view.substr(self.view.line(region))
            row, col = self.view.rowcol(region.begin())
            while col >= len(whole_line) or whole_line[col] in VALID_FILENAME_CHARS:

            m = filename_re.search(whole_line, col)
            if m:
                filename = m.group()

                self.view.window().open_file(filename)
            else:
                print "No filename discovered"

It throws

Ive read in ST release notes that it uses python 3.8 now, but stack trace is using 3.3.
But! It seems that it installed 3.8 as well:

Packages|⇒ ll /Applications/Sublime\ Text.app/Contents/MacOS/Lib

2.9M May 20 10:57 python3.8.zip

Yeah, this is python 2 style prints. Maybe if you change them to print() style it will work.
