I know it's not helpful to say "well it works for me", but...."well, it works for me". I'll try and be more helpful:

I have several Windows computers - all four now running Windows 11. In all cases at the minimum Bluetooth keyboard and mice are used all the time and in all cases it works absolutely fine with no faults. This is with decent, high-ish-end-branded devices (Logitech, Microsoft) and generic nonsense from Amazon.

I use Bluetooth earpods - cheap things from Amazon - with my phone and sometimes my laptops again without issue. The very worst that will happen is that it won't connect one time, I'll put them back in the case, take them out again and it will work fine. I've had three bluetooth earphones/headphones before this and all have worked the same.

So I wonder if this is something about the specific kit you use (or you've been very unlucky, or I've been very lucky). Or a specific other condition of the environment you're in, e.g. very high interference on the 2.4GHz band. Are you able to check this by moving these to a very different location? Or have you a friend with a Windows laptop who you could try the devices on? If you cannot connect a single BT device to a Windows device under any circumstances that does seem highly unusual and likely to be about something else.
