Can't reboot Teensy 3.2 Ty 0.9.8 on Ubuntu 22.04

After a long hiatus I am back to using Tycommander 0.9.8 on Ubuntu 22.04. The reset button always draws the error "failed to reboot board 'XXXXXXXX-Teensy', but sometimes it does actually reboot. I'm loading manufacturing test code which has a 3 second timeout waiting for the Serial port to open, then prints some information about the code - so that's what I expect to see after clicking on the reset button.

Trying to understand this more, the serial port connection indicators are not reliable. When showing the port open it sometimes isn't. Also if I click reset repeatedly it goes through a repeatable cycle of connecting to the 'bootloader', then 'running' (with serial port indication not always correct). Eventually it will display the expected serial output. If I cause a hardware reset (i can do this on our custom board) that works as expected. It's just the reset over USB that is flaky.

I have a similar problem. Did you find any solution in the end?
