Integrated Camera and Bluetooth stop working in Ubuntu 20.04 after a while

I am experiencing some issues with webcam and Bluetooth in Ubuntu. I have a Lenovo Thinkpad E595 with Ubuntu 20.04 from a fresh installation and up to date. Whenever I boot the machine all my integrated peripherals are working fine: I can connect to other devices using Bluetooth and the integrated camera works well. However, after a certain amount of time (more than several hours), these two components mysteriously stop working and are not even detected by the machine. My computer is on a fixed position and I rarely close the lid, so I don't think it has to do with loose cables.

I am wondering if anyone is experiencing the same kind of issues (it seems to be similar to another question posted here , which would explain the time delay); I'd be happy to hear if anyone has a guess on what is happening. At the moment I can't think of any more relevant information, but I'll gladly provide if needed.

Should I report this as a bug? I was waiting to see if it could be narrowed down to a specific aspect of the system (kernel, module, ...).

Below some outputs:

Running dmesg at the startup shows the different devices detected

[    1.572633] usb 3-2: New USB device found, idVendor=5986, idProduct=2130, bcdDevice=56.09
[    3.570861] uvcvideo: Found UVC 1.00 device Integrated Camera (5986:2130)
[    1.272893] usb 3-1: New USB device found, idVendor=0bda, idProduct=b023, bcdDevice= 2.10

Nothing related to these devices seems to be tracked in /var/log/dmesg after the incident, unfortunately.

Thanks in advance!
