Works fine for me on Ubuntu 21.10 and using the latest driver from the download page. Did you try complete removal and fresh installation?
Code:
lsmod | grep evdi
evdi 61440 5
drm_kms_helper 262144 2 evdi,i915
syscopyarea 16384 2 drm_kms_helper,evdi
sysfillrect 16384 2 drm_kms_helper,evdi
sysimgblt 16384 2 drm_kms_helper,evdi
