Bluetooth and usb 1-4 failing with the mt7921e wifi/bluetooth card.

I have been an arch linux user for the past 6 months and everything has been going well execpt of suspend. from october to november, nvidia preserve memory feature resulted in a black screen after wake up. from november to december the linux kernel itself failed and resulted in a black screen. but now i finally stopped the black screen by just creating swap but their is one last problem, the bluetooth. whenever i wake up my computer the following messages show up(i used the -r flag for journald).

Mar 12 13:38:35 archernitro5 kernel: usb 1-4: Failed to suspend device, error -110
...
Mar 12 13:38:32 archernitro5 kernel: Bluetooth: hci0: Failed to set up firmware (-110)

Mar 12 13:38:07 archernitro5 kernel: mt7921e 0000:05:00.0: Message 00020007 (seq 6) timeout

the wiki came to no help as the solutionbs either did not work or it was desktop exclusive while im using an acer nitro 5

Do you have the latest version of "linux-firmware" installed?
