No - this was not a known issue.
The change in the versions that work to it not working are changing the ide from esp-ide 2.x to 3.x
There is a recent release of 3.1.3 which I'm currently testing - this might sort the random rebooting.
I'm not sure if there will need to be changes to the serial driver to get the settings to work - @JumJum - any ideas?
