Bluetooth only works if reboots

So i got a baseus bluetooth dongle and it works fine, the devices have good conection etc. but the bluetooth only works when i reboot it, if i'm in a cold start it does not work, the bluetooth service is always running fine.

i've found that other people have the same problem related to the kernel after version 15, where their bluetooth only works when rebooted. i'm running on kernel 5.18 but i have a laptop running 5.17 that is working just fine, so i don't think it's still a problem with kernel
