How to fix Windows Sandbox failed to initialise. Error 0x800736b3. The referenced assembly is not installed on your system

Joao Monteiro 5

I want to run Azure Synapse Analytics labs but the button for the Sandbox does not appear.

When I try to run the App directly I get the error indicated in the Title.

I have installed Windows 11 Pro Insider Preview.
What I have already done to try to solve the problem:
Windows + R and run optionalfeatures;
Unselect Hyper-V; Unselect Sandbox; Restart; Select Hyper-V; Unselect Sandbox;

Thanks
JM
