After firmware 1.4.2, projects made in the previous firmware cannot be opened.
The boot process begins, then everything freezes, you have to unplug the power cable to turn off the device.
If you have a project to share, I’d be happy to try to load it on my end.
When I’m near the device I’ll send you the project
This is the project
I’ll give it a run tomorrow and see if I can reproduce your issues. Thanks for sharing. Happy holidays
