I have installed Ubuntu 20.04 on an older laptop that used to run Windows. When running Windows Bluetooth was stable. On Ubuntu 20.04 Bluetooth powers off after using the laptop for some time. Sometimes its ½ hour, at other times several hours, but then, suddenly, Bluetooth gets powered off and cannot be powered on again.
I have tried using bluetoothctl to turn the power back on again, but I get different answers. Sometimes it says "Changing power succeded" even though it does not, at other times it says something like failed (will add the correct line when it happens the next time).
My system configuration is as follows:

I have been running Windows my entire life, and this is an attempt to switch to Linux. I must admit it has been made a lot easier then before with this build.
I would really like to solve this issue and will provide any information about the system needed to aid me.
Recently I got this message after 45min of of bluetooth being connected:

Can't really figure out what that should tell me, but I ran the update too. I'll be testing during the day to see if that solved the issue.
UPDATE: Unfortunately the issue persists after updating the driver.
Machine has been turned on for more the 24 hours, just being idle.
Rebooting - wishing there was a way to reconnect bluetooth without having to

You can install the new one by
And reboot the system
