I think i'm having some issues with my bluetooth driver. The following commands were ran:

The last thing I tried was from this link: Bluetooth (rtl8723be) does not find devices on Lenovo Ideapad 100-14iby
However i got stuck here and i have not ideea how to proceed(noob here): make
make -C /lib/modules/6.2.0-36-generic/build M=/home/.../bluetooth-5.4 modules
make[1]: Entering directory '/usr/src/linux-headers-6.2.0-36-generic'
ERROR: Kernel configuration is invalid.

Run 'make oldconfig && make prepare' on kernel src to fix it.

L.T: I've changed the direction a little bit and now i'm trying this:
https://github.com/HRex39/rtl8852be_bt#3-save-and-build from here Not finding bluetooth devices | Ubuntu 20.04.5
However now i have the following issue:
sudo apt install --reinstall linux-headers-6.2.0-36-generic
make
make -C /lib/modules/6.2.0-36-generic/build M=/home/.../new_attempt/rtl8852be_bt modules

Can anybody help me fix this somehow? Note that in Ubuntu Cinnamon devices get discovered, especially my headphone and I can pair from either the command line or from some Bluetooth manager, but there is a lot of sound stuttering which is unplayable regardless of my "efforts" in trying to fix the problem from other available resources. Please let me know if more information is needed. Thanks!
