------------------------------------
I changed in file '/etc/default/grub' the lines:
GRUB_TIMEOUT_STYLE=menu GRUB_TIMEOUT=-1
I used the command 'sudo update-grub' and Reboot the computer. The grub menu is now shown and I can still use the internal keyboard.
I can choose between kernel version:
- Linux 6.5.0.-1019-oem - Linux 6.5.0.-1018-oem
When I choose the kernel, 1019, the keyboard does not functions after booting When I choose the kernel, 1018, the keyboard workes after booting.
So this shows that the problem is caused by the 1019 kernel.
