how do i flash back to the latest version? do you have a link?There's no such thing, and this isn't XDA.
You need the specific April Security Update for your speciifc device. You can find that on XDA, probably, if your phone can even downgrade.
ok.

Go here, download the firmware for 'TMB' (it's the same as the AT&T firmware). https://updato.com/firmware-archive-select-model?q=SM-N960U&rpp=15&order=date&dir=desc&exact=1
I leave you to Googling and YouTube for the rest, for how to extract the firmware zip and how to use Odin.

If your bootloader version updated there is no going back.. Atleast I think thats the case with all android versions?
Well im just saying...Samsung hasn't updated the bootloader version for the Note 9 in a very long time. They don't have a serious anti-downgrade protection.
