Hello, i just managed to get the beta up and running ..
Also had issues with old setup...crashing.. was solved by the renaming trick .. ( in appdata/roaming... )
Observations here:
Changelog wrong...still 3.1.0
Still does not remember where it last saved Gcode.. default to nonsense "usbdrive" location instead of FOLDER . This i saw discussed in 3.10 threads..
I think the slowdown issues after slicing got a bit better at least here... will test later with a bigger model..
