Upload from VMicro go to bootloader while Arduino upload works (Read 1318 times)

	I am using an Adafruit Feather ESP32-S3 Reverse TFT. I am trying to upload the WiFiScan project. When I do this with through VMicro in Visual Studio, after uploading, when I reset it goes into the bootloader (with the associated blue, green, and orange screen, no COM port, and a virtual drive). This previously worked successfully and stopped working just after I had made a small code change. So I've gone back to the WiFiScan project which has the same results in Visual Studio. When I then try it with the Arduino IDE (2.2.1), after the upload, I reset and it runs successfully and I can see the output on its COM port. I've tried restarting Visual Studio but that didn't help. Has anyone seen something like this before? Any help would be appreciated.

	It seems this could be an intermittent issue related to the ESP32 Board Package and upload tools from the below issue on GitHub: https://github.com/espressif/arduino-esp32/issues/6762 Are you using the exact same code and board package in the Arduino IDE? Does reversing your small code change help resolve the situation?

	I tried backing out my changes which had no effect. As I said, I went back to the WiFiScan example project (with no changes) which previously worked with VMicro in Visual Studio but does not work now. The WiFiScan example works consistantly with the Arduino IDE (2.2.1). I am aware of the problem described in the bug referenced by the link you sent. When I program my ESP32-S3 I need reset the board after uploading to get the code to run. That's not the problem. The problem is that after successfully programing using VMicro with Visual Studio it goes into the Bootloader thing. The display shows (looks like this https://jamesachambers.com/wp-content/uploads/2023/03/ESP32-S3_Bootloader.webp) and I get file share explorer window but not a COM port. Any ideas how to diagnose this problem?
