libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib64/dri)

I'm trying to run an app on Fedora 33, but when I run the executable, I get this error:

error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib64/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open swrast (search paths /usr/lib64/dri)
libGL error: failed to load driver: swrast

  Major opcode of failed request:  149 (GLX)

I tried following the thread here: https://www.reddit.com/r/Fedora/comments/hhytvl/libgl_error_mesaloader_failed_to_open_iris/ but haven't gotten anything to work Note that the driver iris_dri.so is present in both /usr/lib/dri and /usr/lib64/dri Any help is appreciated, thanks in advance!
