Failed to connect to ESP32

[mkremer]

Since I installed Arduino IDE and ESP32 packet on my PC, I can no longer flash with VS Code or ESP-IDF. Build works, but the connection to the ESP32 only works sporadically.

Everything worked perfectly before without Arduino IDE. I only installed the Arduino IDE to have a look, but now it seems to have broken everything.

Can someone tell me where the problem could be here? I uninstalled Arduino again, but the problem still exists.

Can it be that there is some connection between Arduino IDE and VS-Code or something?

---------
Sometimes flashing works after a new build. But it takes longer than before.
