Hello, I wanted to give you all hopefully some help, I am not from the company, But I just had that issue plague me for several weeks, and I seem to have found out what the cause was and fixed it..
I tried removing all the old app and getting it again and re-running the USBmonitor application in the 35inchENG folder, and still had the issue, I ran it also as Administrator and same issue Sensor Inite Failed, then I went another step, turned off all the Windows Virus Protection and tried again. and it finally connected and the screen came on with all my info I had previously setup, it seems to have been caused by a recent update to the windows virus info, I am currently at the most recent windows updates as of 11/17/2024 and this happened right after the most recent windows update.
I hope this helps you figure out your problems too!
