Instead try:
sudo apt install dh-sequence-dkms debhelper build-essential devscripts
git deborig HEAD
dpkg-buildpackage -us -uc
sudo apt install ../rtw89-dkms_1.0.2-3_all.deb
I got those commands directly from the GitHub page I linked above.
Looking up dh-sequence-dkms, it looks like the package first appears in later versions of Ubuntu and in Sid.
I am in the middle of other work right now - please allow some time that I can look into this later or another forum member can provide some help.

Well, I know you are on the 6.3 kernel.
Can you also show the terminal output for
sudo lshw -C network
Let's try
lspci
The lshw command gives a very generic response in this case.

That shows RTL89... Which we tried in post 1 of this thread.
There is a minor difference: lwfingers is directed toward 8851... Your Arch screenshot shows 8852be
We can try:
#Turn off your Security Boot in BIOS
git clone https://github.com/HRex39/rtl8852be.git
cd rtl8852be
make -j8
sudo make install
sudo modprobe 8852be
