There's now a new version available:

https://patchwork.kernel.org/project/linux-wireless/cover/20211026041616.4956-1-bqiang@codeaurora.org/

If you can, please do test the version in the master-pending branch
(commit 9a914cfdbfd69):

Most likely this should fix it. You could also try changing your BIOS
