You need to post your gpu brand and model.

See How to provide good information

all graphics information with inxi -F :
Device-1: Intel Core Processor Integrated Graphics driver: i915 v: kernel
Display: wayland server: X.org 1.20.10 driver: loaded: intel
unloaded: modesetting resolution: <missing: xdpyinfo>
OpenGL: renderer: Mesa DRI Intel HD Graphics (ILK) v: 2.1 Mesa 21.0.1

As I suspected it does not support wayland server yet.
