Bluetooth only allows me one controller at the same time

[Beeble]

Greetings,

around ca. 4 weeks ago my MiSTer won´t accept a second bluetooth controller anymore.
I usually use the Retrobit Saturn BT Controller and it works as usual, but no second controller will connect anymore.
(SN30 Pro and a PS5 Controller clone - both worked fine before)

If I don´t connect my Retrobit Saturn BT Controller I can connect either the SN30pro or the PS5 Clone but also not both at the same time.)

I tried to re-pair them with F11, the controllers are found but the removing existing pair and re-pairing only works again if no other controller is connected.)

I guess it´s a driver thing?

I have ordered a new BT/Wlan Kombi Stick, lets hope that helps.
