Every time I try to bevel this edge on the left that was made identical to the other edge on the right, it either crosses or only bevels one side of the edge. I have recreated the edge from scratch a few times and I get the same result every time. I made sure there's no doubled vertices and I cant find any weird geometry that is causing the problem either. Just doesn't make sense that one side would work fine while the other glitches out. Project file

As you see if you display the faces orientation, you have flipped normals, so before the bevel, select all and press ShiftN:
