Windows 10: High Pitched Noise from Headset

Hello,I am having problems with a high pitched sound coming from my headset whenever I start my windows laptop. It just recently started happening, but when there is a bluetooth device connected, it works normally. My headset also works when connected to other devices and computers. I downloaded the recent version that fixed the patch not too long ago OS Build 19041.1151 and the problem still kept going on.I chatted here about my issuelink and they told me to come here. Not quite sure if I am posting in the right section, but if anyone could help, that would be great. Thank you!

High Pitched Screching Noise

My pc is making a high pitched screeching noise and I can't make it stop without muting the volume. It doesn't start until I increase the volume to 100%. In the meantime, I can hear my hitting keystrokes or tapping on the pc echoing back through the speakers.
How do I make it stop doing this? I'm not sure what I did to make it start doing it. It also make a high pitched noise when I close the lid until it shuts off.
