Context information (for bug reports)

• Output of pyinstaller --version: 5.0.dev0

• Version of Python: e.g. 3.9.1

• Platform: Arch Linux, Linux-5.10.15-zen1-1-zen-x86_64-with-glibc2.33

• Did you also try this on another platform? Does it work there?
  Tried on arch on another desktop with freshly installed pip, pywebview, pyinstaller. No luck.

  • start with clean installation
  • use the latest development version
  • Run your frozen program from a command window (shell) — instead of double-clicking on it (no program)
  • Package your program in --onedir mode
  • Package without UPX, say: use the option --noupx or set upx=False in your .spec-file
  • Repackage you application in verbose/debug mode. For this, pass the option --debug to pyi-makespec or pyinstaller or use EXE(..., debug=1, ...) in your .spec file.

Same goes for import flask. Getting same error if I import anything except default modules.
EDIT: I remember updating my system before I started getting this error. I am sure this was working fine before update. Is there any more info I can provide?
