No flashing possible on Shelly 1PM

[tmonxx]

Hi.
sorry but I can't flash my 1PM.
{"status":"updating","has_update":false,"new_version":"20221108-153925/v1.12.1-1PM-fix-g2821131","old_version":"20210429-101828/v1.10.4-g3f94cd7"}
I tried to flash older versions of shellys own firmware. It's working. Now it shows me to update to the newest.
But I can't flash tasmota on it...

The same with the Shelly L1, it responds but no network is created.
