On Win10+vscode platform, I tried to use jlink to debug esp32, but I ran into some trouble.
When I gave debugging to a project under development, it was first compiled (Pre-Debug) in the terminal and successfully compiled, but then it was compiled again at the debug console and when its compilation was done, the following error was reported when it was supposed to do firmware burn-in.
Pre-debug:

When I create a new empty ESP32 project for debugging, the debugging function works fine and it only compiles once (at Pre-Debug), after which its not recompiled at the debug console.
I would be grateful if you could help me!
