Buzy bar since lb2?

Hello, it’s been two days since my laser bugged, I didn’t touch anything before the bug,
I tried changing the USB cable, USB port, reformatting Windows 10, CH340 at least 5 versions, power supply and all the classics like USB standby, switch limits are ok, etc.
my laser is really having trouble connecting he puts me spyvent the bar certainly busy when I touch nothing! Here are my screens.
the green bar busy

The console in two parts

My settings

i went to twotrees to find a firmware, but it won’t flash with mkstool. fed up with all these bugs, everything risks going out the window, Is there a real solution? I should point out that it worked fine before I turned off my PC it didn’t work anymore, on another new PC it’s the same, with lb2 too (it’s possible that it’s bugged since I installed lb2, I don’t know) I thank you very much in advance I am desperate…

Try loading a prefs backup

After that when everything is working create a user Bundle:

.
You can also try an older version (1.6.03 or 1.7.00):

thanks but it didn’t work, sometimes it connects well, I touch something like trotting 10mm and it hits the buzzy bar and it freezes

That’s a USB communication issue in most cases. Those errors are typical in that case. Exchange the USB cable and remove all electrical disturbances.

i did it a lot of time, 2 new usb cable high quality,try all the usb ports on 2 pcs,etc, i can’t find the twotrees ts2 10w bundle anywhere because I formatted my PC, I even tried Windows 7, 10 and 11. Impossible to flash the firmware provided by Twotree, but I know that the machine works, from time to time it connects me, sometimes it homming and sometimes I intervene it’s buzzy bar. disturbances, I made 2 or 3 posts on it.
