ACPI-call crashes on apt upgrade in Ubuntu 22.04

Hi guys
I need your help :) ...
I have a Thinkpad X1 with an Ubuntu 22.04.
When trying to run

apt upgrade with a 5.15 Kernel I face this error:

$ sudo apt upgrade

  ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.

make: *** [Makefile:750: include/config/auto.conf] Error 1
make: Leaving directory '/usr/src/linux-headers-5.15.0-56-generic'

Is there something I can do to fix it? I tried
$ sudo apt install --reinstall linux-headers-$(uname -r)
but it didn't really help.

Thanks for your help.

best
