So i built a outdoor hoop antenna to replace my cheap and crapy walmart antenna. IDK if the pre-amp fried the 5g/LTE filter or it wad my diy antenna. Is it possible for a 5g/LTE filter to stop working and filter out every channel. I orderd a new filter to see if it is the problem. Here is the antenna tutorial I followed: https://youtu.be/Tg0JjeotXq4 And the 5g filter: https://a.co/d/gwpNo2g

Is the pre amp powered over the coax? The filter may not be designed to handle power.
Nearby lightning could have fried the filter. A direct strike is not needed to cause damage.
It could just be terrible build quality. The filter could have had a bad solder joint that cracked.

Dam, my old antenna was powered over the coax. That's probly what did it.
