AllowBoxedJobs=y does not work for Chrome

Testing AllowBoxedJobs=y for the first time ever and it doesn't work for me in my Windows 10 x64 21H2 computer.
At launch, chrome forms only a blank page and nothing else happens thereafter.
It doesn't crash or closes itself, only a static blank page or window.
Chrome is installed in the system.
Sbie+ 1.9.8
I have 8 chrome's user profiles.
chrome.exe is not forced, it runs from a shortcut, one for each profile.
Red box.

Works for me (on Win7 x64 but should not matter). You may want to create a new red box to test it.

 

Created a new one, it didn't work.
Well, only setting it as a Green Box works out.
Any other box type gives a white blank window.

 

What happens if you run from the context menu (and not from shortcut):
RightClick chrome.exe => Run Sandboxed => Your Red Box Name => OK

 

Same story.
