I have the same problem! There some way that I can help to fix this?

[5kft]

I've submitted a PR that should fix this: https://github.com/aircrack-ng/rtl8812au/pull/699, hopefully they'll merge it soon. I'm using a local patch on my kernel builds in the meantime...

[krishna-sharma]

I can confirm that the fix from @5kft in PR #699 works. Thanks @5kft :+1:

I am on Ubuntu 18.04 with HWE stack and started seeing this error recently after a kernel update.
