running scrcpy and USB tethering at the same time on ubuntu

long story short, I have Ubuntu on a USB as a persistent install and using my phone USB tethered for wifi.

had a lousy idea I wanted to test out and reformatted my USB to another distro. didn't pan out so I reinstalled Ubuntu and now I can't use scrcpy and bt tethering at the same time. only one or the other.

when I have tethering on, I get an error message on the terminal that "adb push returned a value of 1" or something to that effect.
if I start scrcpy first then enable bt tethering, scrpy will close.

i don't believe I made any changes on the phone itself, and testing out the setup on a windows install it works with no issues.

Anyone have any ideas, or can point me to the right direction?
