You say it was working first on Zorin then at some point not working. True/False?
If true, I am wondering if the dreaded kernel 6.17 update could be responsible.
Have you tried rolling back to 6.14 kernel?
From grub menu:
select "Additional Options for Zorin"
then select a 6.14 kernel generic option that should be listed.
try boot with that kernel and see if any difference.
EDIT: I have now stumbled on this thread. Zorin Not booting after restarting - #7 by AndreiZorin
Can you confirm re-installation has fixed everything here?
