Sorry for the slightly delayed reply. Normally, piOS comes with kernel-headers pre-installed. For example, here is a screenshot of my current system:

I suspect that you might have updated to a newer minor version of piOS, which caused this issue. The current major version of piOS should be 6.12.47.

@veye_xumm yes, it updated to 6.12.57, but this problem also was in 6.12.47 that it was updated from.
How do I get the headers?

My Raspberry Pi comes with headers by default. You might want to reinstall piOS? We've already released the 6.12.47 ko file on GitHub.

@veye_xumm I tried it before. Right now reinstalled Pi OS from Pi Imager, no kernel headers, so problem not resolved.

@jambojettt Just checked, I have a 64 bit version, just to be sure.
Kernel headers are installed.

@jambojettt
Did everything step by step on the github page. The kernel thing didn't work. Don't know what to do next. dmesg didn't work

Normally, the PiOS you installed comes with kernel-headers. Could you tell me which image link you used?
Can you help run this script and send me the results?

uname -a
ls /usr/lib/modules/
ls /usr/lib/modules/$(uname -r)

[jambojettt]

@veye_xumm
Wrote them, sending the results.

Sorry for reply late.
I see that your raspberrypi-kernel-headers are installed. You should be able to directly run make in the driver source code directory.
