Xiao ESP32-c3 abnormal behavior, Arduino IDE

I've designed two devices to work on the Xiao Esp32-c3 processor. I literally can't explain any of this, but I'm going to try to convey the information.

One of the devices has resistors to ground on D4 and D9, which are also connected to switches. So far, I've been simply trying to read the switches, but the device also has IR receiver functionality. Now here's the kicker: without those resistors in place, I'm able to upload a sketch, or it seems to upload the sketch, occasionally it works, mostly it doesn't. But here's the main issue. The minute I had a problem with the first one, now every sketch I try to upload to any XIAO esp32-c3 is wonky in some way or another. I've got an IR receiver sketch that has always worked, and somehow the board or program now misinterprets the IR signal. Half the time, Serial output is available at the Monitor, other times it isn't.

I seriously can't make heads or tails of this, I only know that once one single esp32-c3 messed up, every single other one of them that I try to use also has a problem.

The problem is too loose for me to understand what is going on.

After writing a simple matrix to check all the digital I/O pins for input, it turns out some of the pins are defined incorrectly somewhere. For now, I've got it working by referring to pin 4 as pin 6.
