This is not actually a PostGIS problem, it's a problem with our yum repository packaging.
The problem is that postgis, through gdal, ended up being linked to two different versions of proj at the same time.
You can check it by doing:
ldd /usr/pgsql-13/lib/postgis_raster-3.so | grep proj
If that shows up two different "proj" libraries, then you have that same problem.
In this case, uninstall the OS supplied "proj" library. If that removes postgis through dependency, let it and then install it with:
dnf install --excludepkg proj --excludepkg proj-datumgrid postgis30_12
... and that should of course be postgis30_13 if you're on PostgreSQL 13...
