I got the same thing and worked around it by installing the previous release.

See https://github.com/qutebrowser/qutebrowser/issues/8389 - unfortunately there's a lot of stupid false-positives especially with PyInstaller (packaging a Python application into an .exe). Happens a few times a year, unfortunately there isn't much I can do other than submitting a report to Microsoft and hoping they'll react ¯\_(ツ)_/¯
