There is only
Version : 21.2.5-1
mesa vesrion in Manjaro repositories on all branches of update gathering.
You showed some further version of mesa. Where did you get it and why not to use current Manjaro version of mesa?
If have no reason to use external mesa package of a bit ahead version, try to install current version from Manjaro repositories:
sudo pacman -Syy mesa
which mesa version you were suggested to install with that command? If 21.2.5-1, then install it.
Have any problem after that?
