Wifi driver compilation Rpi 4B - kernel headers error: "no such file or directory"

hi, thank you, but it doesn’t work. Problem persits:

apt --purge remove rbp464-headers-sanitised-5.10.78-5-osmc

osmc@osmc:/usr/src$ ls -l
celkem 8
drwxr-xr-x 23 root root 4096 čen 13 23:11 rbp464-headers-5.10.78-5-osmc
drwxr-xr-x  9 root root 4096 čen 13 23:50 rtl8812au-5.13.6

The truth is, that I tried to compile drivers without package “rbp464-headers-sanitised-5.10.78-5-osmc” at first. Only with “rbp464-headers-5.10.78-5-osmc”. But it didn’t work. So I tried to install sanitised headers.

root@osmc:/home/osmc# ls -l /lib/modules/5.10.78-5-osmc/

Still fatal error without sanitized headers installed:
