Hi and welcome.
I am wondering if the updates to kernel 6.17 from 6.14 is the issue as there have been a few posts about various things not working after a kernel update. At boot time, if you are using Secure Boot for Windows/EFI, continue pressing the Esc(ape) key to view the GRUB (GRand Unified Bootloader) menu, then choose Advanced options, recovery and you should see different kernel options to boot from. Choose an earlier kernel and see if that improves things.
With regards to the Bluetooth disappearing this happens because if you boot into Windows it uses/generates a different pairing key, so the Zorin one gets lost. I recently posted a possible solution to this issue (it doesn't always work) where you have to copy the pairing key from Windows into Zorin. Will amend this post when I find it.
