Hello PemaYangden-3875,
This is because Environment variable expansion (%username%) is not supported in uninstall command.
Refer to the note under uninstall command from here: https://free.blessedness.top/en-us/intune/intune-service/apps/apps-win32-add#step-2-program
For your case, try using a custom wrapper script within your win32 package to wrap the command and use this script for the uninstall command.
Hope this helps!
