Update.
Now modprobe 8852be works.

Here is what I have done.

Use the kernel source code from https://www.kernel.org/.
In the current case, I selected 5.15.60.

According to https://lore.kernel.org/all/[email protected]/, patch /drivers/acpi/resource.c file, recompile the kernel, to make the keyboard working...

sudo -i
cd rtl8852be
make uninstall
make clean 
make  # Caution, do not use make -j or something alike. 
make install
modprobe 8852be 

As I have mentioned above, though make -j runs a bit faster, modprobe will fail. Not sure why.

The good news is, that both the keyboard and WiFi are working...

Please post any make errors or other errors. I noticed that the modprobe worked after the make and sudo make install. During those steps, I was taken to a sub-directory of rtl8852be. Modprobe worked there, but not in the original rtl8852be directory. I forgot what directory I was taken to though...

OS: Ubuntu 22.04.1
Kernel: 5.15.0-46.49
CPU: R 6800H
Security Boot, disabled.

How do I build the driver?

sudo -i
git clone https://github.com/HRex39/rtl8852be.git
cd rtl8852be
make -j8  # warnings, no error. 
make install
modprobe 8852be

The driver works with the original kernel (5.15.0-46.49-generic) from Ubuntu 22.04.1 LTS (Jammy Jellyfish). The WiFi works.

While, with this particular hardware, the keyboard does not work.
According to https://lore.kernel.org/all/[email protected]/, patch /drivers/acpi/resource.c file, recompile the kernel, results in a functional keyboard, but WiFi fails.

Recompile WiFi driver,

sudo -i
cd rtl8852be
make uninstall
make clean 
make -j8
make install # warnings, no error. 
modprobe 8852be # Report error, modprobe: ERROR: could not insert '8852be': Invalid argument

With the original kernel, modprobe 8852be works.
After patch /drivers/acpi/resource.c file, modprobe 8852be fails.

Please post any make errors or other errors. I noticed that the modprobe worked after the make and sudo make install. During those steps, I was taken to a sub-directory of rtl8852be. Modprobe worked there, but not in the original rtl8852be directory. I forgot what directory I was taken to though...
