The only Windows 10 version affected by this issue is Windows 10 version 1903 and the KB4497936 update which originated this known issue can be received via Windows Update by Insiders currently running Build 18356.30 or higher.
Windows Insiders can also download and install the KB4497936 cumulative update which may block Windows Sandbox from launching from the Microsoft Update Catalog website.
The highlights of the KB4497936 update are the added protections against "speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling" and the addition of "gov.uk to the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge."
I would suggest you remove KB4497936 and check once again
