Smart EVSE is not booting

[2pjnl]

From the start I have had problems with stability and the Smart EVSE crashes regularly. After flashing Release v3.5.0-RC1, this seemed to go better. On my workbench it worked for a few hours without crashing. I then mounted it back in the enclosure and charging went well for a few hours until it crashed again. After a power cycle it would not start again, the screen only flashed once.

After disassembling and connecting via USB-C it would boot, but it crashed again after 9-10 seconds. Now it no longer boots via USB-C. I initially think of a software problem. Is it possible to flash it via USB-C?

Last paragraph, "building the firmware" tells you how to upload via USB-C

Installation was fairly easy, but Git was not in the PATH. After this was fixed, compiling went without any problems, but uploading does not work. I have changed the port to COM3 in platformio.ini, but I get the message below:

If you're sure that COM3 is the right port, and you have a good USB cable, and it is plugged in correctly.... then I don't know what the problem is.....
