ESP32Cam-MB Issues Uploading

I'm having issues uploading any sketches to the esp32cam - i have tried all the fixes holding down buttons etc. to no awail
I am connected via an USB the weird part is that whichever usb port i connect the esp to in my laptop it keeps showing COM-4.
The ESP32CAm is showing wifi too!

I can't help you with ESP32 related stuff but in future please don't post screenshots of code or errors. Please read https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966#posting-code-and-common-code-problems.

Not necessarily weird. Windows USB enumeration works in mysterious ways.

Compilation error: 'std::list' has not been declared

The last error is easy, the current version of the boards is not compatible with ledcAttach and a few others. Here is the screen grab from the Migration document.
Your original error was an upload error on an MB board. I have a dozen or so of those, and they are problematic. Get an FTDI board to do the upload, which has never failed for me.
