Upload problem with Teensyduino and platformIO

[fishercat]

I am having problems uploading to my Teensy 4.1 with teensyduino and platformIO. The upload dialog terminates with "[upload] Error 129". This happens with any ino file or teensy board. My OS is Ubuntu and is up to date. platformIO is up to date. Modemmanager is not installed. Teensy Loader version is 1.52. USB cable is a known good one.

Uploading with Arduino IDE works fine. I do get a reboot failed error, but the upload works.

The verbose output from teensyduino is below
