Trouble compiling/installing the driver

I made an Update of my linux mint to version 21.2. Do not get Connection with Wifi and compiled this code making the following steps:

sudo apt install git dkms build-essential
git clone https://github.com/jeremyb31/rtl8822bu.git
sudo dkms add ./rtl8822bu
sudo dkms install 8822bu/1.1

In the last step I get an error message:

Kernel preparation unnecessary for this kernel. Skipping...

Building module:

'make' all KVER=5.15.0-78-generic........(bad exit status: 2)
**Error! Bad return status for module build on kernel:** 5.15.0-78-generic (x86_64)
Consult /var/lib/dkms/8822bu/1.1/build/make.log for more information.

The make.log:

is missing an ipx/net.h file. Where to search for that file and where to put in?
