Tasmotizer do not start on macOS Big Sur

[typepub]

Hello,

Facing a problem on a fresh install of Tasmotizer:
python3 -m venv venv2
. venv2/bin/activate
pip install tasmotizer
Successfully installed PyQt5-5.15.1 PyQt5-sip-12.8.1 pyserial-3.4 tasmotizer-1.2.1

When starting Tasmotizer, no window appear and Python is stuck 100% of CPU. Have to kill it. Tried to wait for 5 minutes but no window appear and still stuck.

Any idea of what I can try please?

Thanks.

I am having the same issue, did you manage to solve this yet?

No solution found. I used a workaround: https://tasmota.github.io/docs/Getting-Started/#esptoolpy

Use latest pyserial for Big Sur see pyserial/pyserial#509 (comment)
Short pip3 install pyserial --pre --force

The latest pyserial does not fix the issue. Can we reopen this?
