Wouldn't that be a problem of Windows itself? For me bluetooth has been a mess on every Windows machine. It's a miracle if something works and to get something working you even need to buy a dongle with a specific chip on it...
I've definitely experienced what a bad Bluetooth adapter on Windows is like though. Things just failing to pair for no apparent reason, things randomly disconnecting, the thing seeming to forget all previous pairings, etc. I think that's usually been due to poor drivers. Earlier versions of Windows didn't really have much Bluetooth support out of the box, most of the stuff seemed to be implemented by each hardware vendor at the time. Compatibility issues were so common. This has largely seemed to go away especially when using modern Intel WiFi/BT chips and modern Windows.
I mostly use Bluetooth with Apple AirPods. I tried running Ubuntu on the ThinkPad but it had the same problem I've seen on other Linux machines: the AirPods would only pair as headphones, not as a full headset with microphone.
I like Windows better anyway on the hardware, especially its support for different scaling factors on multiple monitors. So I run Linux in a VM or use WSL2.
As with all things tho, YMMV.
