I'm using various distros (including Ubuntu) on my laptop and in all of them, bluetooth disconnects randomly while watching videos or listening to music and refuses to get re-enabled. If I log out and log back in, the option to enable bluetooth just diappears

please give me a solution for this
I was reading through similar problems in this forum including that of Wi-Fi since a few hours.
it got fixed as of now. my wireless adapter (RTL8821CE) had bluetooth capabilities. and installing this "https://github.com/lwfinger/rtw88" and rebooting fixed my Wi-Fi as well as Bluetooth connectivity problems. will be updating if this issue appears again.
thank you
