Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
I understand the issue you have, there is nothing to worry I am here to help, and yes, technically it should work fine on Windows 11, since you experience issues with the app I suggest following the steps below:
Method 1. Repair the 3D Viewer app
On Powershell(admin), copy and paste the command below:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Then hit Enter.
Once done, open Command Prompt (admin), copy and paste the command below:
PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *Microsoft3DViewer*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}
Then hit Enter, once the process is done, restart the PC and check.
If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
Kindly follow the steps from this link:
