right end of Minesweeper screen does not appear

Heya FlipperSteak758.

Sorry to hear the trouble you're having! Have you tried starting a new game to see if this trouble pops up for you again or are you still stuck on this level? It sounds like it may just be a small hiccup that is preventing the blocks to appear for you.

Right-click on Minesweeper and click Uninstall.

To reinstall you can search for it with Games or Store, or just start typing the word Minesweeper at the Start menu screen.

From WINVER:
Version 21H2; Build 19044.2728

I eventually ran the in-place upgrade and, after a very long time, the current version of Win10 was installed on my computer. There was an immediate problem: no cursor. I pushed the power button, shutting down my computer, and then waited about 5 minutes, before restarting. The cursor was there.
I then ran a couple of programs, including games. They worked, but seemed to load more slowly than I remember. Probably because of the new Win10 download. Did a restart. Tried to load Minesweeper. Got the same results as before: initial screen appeared but a couple more minutes until the Minesweeper options appeared. Once they appeared, they seemed to work OK. I repeated those steps several times: restart; load Minesweeper, wait some time before the game options appeared. One last item, something I had mentioned previously: A few seconds after the initial Minesweeper page opens, the was a quick flash/interruption. The screen turns black for a second, two seconds at most, then returns to the whit, initial Minesweeper page. One exception was, instead of the black screen, the Minesweeper options screen appeared, but only for a second or so.
Any more ideas?

Thanks.

I have the same problem on my home PC: both in Minesweeper Adventure mode, and in Treasure Hunt. I found a work-around. Near the end of the game, ne should get out of the full-screen mode, and make the game field as narrow as possible - on my screen it is
about 4 inches wide. Then the black portion of the game becomes very narrow, it allows to play and does not obscure the exit.

Sorry for the delay.

I just tested this again. I logged out of my Xbox Live account and into the generic "Games" account. Minesweeper Adventure mode still works.

But in my Xbox account it does not. I get the green screen for a few seconds and then back to the Start screen. Hovering the mouse in the left hand corner shows Minesweeper running, but if I bring it back it drops back to the main screen.

Adventure is still a no go for me.
