There is a known samba issue. See the GitHub, that we are working through. You can go to the shares directly. The browse is the issue.
LE11 is a ways off.
from a hardware support perspective - it sounds like nightly was working fine? <please confirm> Happy to help work through this - but this needs to be step 1, and ensure stability. We have had good success with Intel Gen11 CPUs with nightly, so will want to check this is ok in your hardware first, with your motherboard hardware.
As you indicated - something blew up, was that adding some of files back manually? (🙂 my crystal ball is broken without seeing logs….)
If you are assembling a Frankenstein software then you will need to be able to stop kodi, move the .kodi directory out of the way, start kodi, and try, try again.
Check the journalctl and kodi.log, etc ….
