Powershell Onedrive uninstall script, file not found

I'm trying to make a powershell script to uninstall Onedrive from users computers by running Invoke-Command -computername computer1 -filepath script.ps1 but i keep getting issues with the last step. The first function "doUninstall" works just fine, it runs it and so on. But the second one "douninstall2" doesnt work, it cant run the file Anyone have any ideas what im doing wrong and how to fix this?

When i try running it using Start-Process -filepath $UninstallCommand -ArgumentList "$EXEArgumente" -Wait I can see the process starting on the target computer but it closes immediately

C:\Users\myuser\AppData\Local\Microsoft\OneDrive\23.002.0102.0004_5\OneDriveSetup.exe  /uninstall

I've tried multiple solutions, like adding "" around the path, adding in invoke-command inside the code but nothing works for me.

uninstall-package wont work for me here.
