Bricked Build After Thunderbolt Card Install, Only Showing Prohibited Sign

I just tried installing the Gigabyte Titan Ridge Thunderbolt card in my Gigabyte Z390 Aorus Pro Mojave build and now I can’t get past the bios. It flashes an Apple boot logo then switches to a Prohibited Sign. I removed the thunderbolt card and all connecting cables but it still won’t boot past the prohibited sign so I’m not sure if I somehow messed something else up.

I disabled -v and set the clover boot menu to fast boot a while back so I’m not sure how to even get into my clover boot menu to try to figure out what’s going on.

The computer works fine in the bios but just can’t seem to boot into macOS. Any ideas how I might be able to troubleshoot this?
