For some reason, the sandbox version still doesn't work for me, even with a brand new laptop with much higher specs. I believe it has something to do with Windows 11, and probably because I have it configured in a way that is some way incompatible with the sandbox version of this game, which causes issues like the one you've mentioned? At least that's what the Devs and people on Microsoft forums think. Unfortunately, I've still got no idea what part of Windows 11 is causing the issue, but I suspect it's something I wouldn't want to dispense with anyway. So yeah, it looks like I'm stuck with the VN version (at least until Windows 12 is released) even though I'd prefer to play the sandbox version.
Now, I'm not suggesting that's why you have the issue you mentioned earlier. It's most likely just a bug. But some people like me, have reported continuing issues, even after the bugs have been corrected, allowing most people to play. And after trawling the Microsoft forums, I eventually came across other people who had issues with games similar to mine, and the problem was caused by certain updates to Windows 11. The problem for me, and those other people who are affected by this issue, is we are only a tiny number of Microsoft's customers, which means that correcting that issue is a very low priority (it needs to potentially affect millions of people before it gets serious enough to be corrected). But hopefully, when Windows 12 is eventually released in 1-2 years, it will no longer be an issue?
