when i do the command makepkg -si, all i get is this.
==> Making package: vmware-workstation 16.1.2-3 (Sat 07 Aug 2021 02:37:58 BST)

error: target not found: vmware-keymaps
==> ERROR: ‘pacman’ failed to install missing dependencies.

How to fix?
Why no install vmware from the AUR?
pamac install vmware-workstation
Also there is this guide
pamac install vmware-workstation 
Error: target not found: vmware-workstation
and that is what i am following
Try
pamac build vmware-keymaps
then run the PKGBUILD script again.
here it is:
vmware-workstation: /etc/vmware-installer/bootstrap exists in filesystem
vmware-workstation: /etc/vmware-installer/database exists in filesystem
vmware-workstation: /etc/vmware-vix/bootstrap exists in filesystem
vmware-workstation: /etc/vmware/bootstrap exists in filesystem
Errors occurred, no packages were upgraded.
==> WARNING: Failed to install built package(s).
To be able to install vmware - you need to do it the Arch way.
Read the guide linked 
unless something has radically changed it will work.
For your other issues - fix them - before you implement what is in the guide.
