We have tons of simplified examples of idealized theories with fixed points. The community at large has worked a lot on empty space-time, just pure gravity. Actually, most of us work in an even more simplified setting where there are only quantum fluctuations of space, rather than fluctuations of both space and time. But nevertheless, people have tested this in literally hundreds of papers and found very robustly that this fixed point where things stop changing exists.
