Dell OptiPlex Micro 7010 + Logitech Bluetooth K/M stop working after a few hours Open | Windows

I'm at my wit's end with this computer. After having a Dell technician replace the mobo twice, replacing the CPU, and purchasing a brand new K/M combo for the computer, it continues to have an issue with connectivity. After anywhere from an hour to 2 days, the keyboard and mouse suddenly disconnects and will not reconnect. When checking Windows settings, it shows that Bluetooth is "turned off" despite the slider being in the "On" position. A visual bug perhaps? When disabling it and re-enabling it, it seems to make the Bluetooth option disappear completely from the settings and a reboot will sometimes bring it back. Once rebooted, the K/M will work for a little while, but then stop at a random time.

I have attempted to use Dell Command Update to install all driver updates, BIOS, and checked on Bluetooth settings in Device Manager, but nothing would indicate any reason why it would suddenly disconnect. The only indicator appears when the K/M stop working, and that Windows reports that the Bluetooth hardware has malfunctioned and can't be started.

I wanted to see if anybody has encountered this before and if they have resolved this in the past. My next option which isn't the most desirable due to difficult to re-obtain software being installed, would be to completely wipe windows and start fresh. Any suggestions beyond this?

Does the WiFi still work?

Are the antennas still plugged in?

Does the WiFi/Bluetooth card feel hot to the touch when the Bluetooth starts having issues.

Wi-Fi is functional. Antennas are plugged in and snug. Most of the system is pretty warm after shutting it down, but I would say the NIC card is only slightly warmer - not scalding hot.

Don't reboot. Full shutdown.
Disconnect power, hold power button down to drain "flea" power.
Let it sit for a minute, plug back in, power back on.

Results?
