Trying to flash a new Marlin build like I’ve done before (on a different PC though), but its showing the error in the title. Brand new VS Code download (with Platform IO and Auto Marlin Build auto installed), but I can’t upload the new edited, firmware to my Arduino Mega 2560 with a Ramps 1.4 Board.
This is the full terminal output

When the printer is unplugged, the PlatformIO Home Tab just shows COM1 under devices. When I plug in the printer, my PC makes a sound…but refreshing the device list in the PlatformIO Home Tab shows no new com port…like it doesn’t even see my Arduino Mega 2560. Why? I can’t see a driver I’m missing online.
Edit: Nevermind, the refresh button doesn’t actually do anything. COM5 does in fact come up. BUT WHY IS IT ACCESS DENIED for VS Code? I even tried launching VS Code with admin priveledges.
Edit 2: I don’t think a missing driver is the issue as Device Manager shows that COM5 is in fact an Arduin Mega 2560.
AAAAND I fixed the problem myself. If anyone has this issue in the future, here was my issue: some unknown serial monitor was for some reason using that COM port (5 in my case) immediately. No idea why. To fix it, I went to Device Manager, found my Arduino under Port > COM5 then Right-Click > Properties > Advanced Settings. From here, I manually changed the COM Port from 5 to 100 (you can pick any number lol).
I don’t know how to figure out what was using my COM5 port as soon as it was plugged it.
