Brief description of the issue:

Each time I ALT+TAB out of the sim to another window for some time, I cannot ALT+TAB back into the sim. Microsoft Flight Simulator.exe is still running in the background but doesn’t react anymore. Neither the Task Manager, nor ALT+TAB or clicking the Window in the Task bar works. Also closing the MSFS Windows is only possible via “End Task” in the Task Manager

Provide Screenshot(s)/video(s) of the issue encountered:

Detailed steps to reproduce the issue encountered:

Simply use ALT+TAB to exit the Flight Simulator Window and try to reopen the Window after a while.

PC specs and/or peripheral set up if relevant:

Windows 10 22H1, AMD 5950X, RTX 3070, 64 GB Ram

It is a Windows 10/11 function.

What is a Windows 10/11 function?

Alt-Tab - Wikipedia).

Alt+Tab is the common name for a keyboard shortcut that has been in Microsoft Windows since Windows 2.0 (1987). This shortcut switches between application-level windows without using the mouse; hence it was named Task Switcher (Flip in Windows Vista).

Thanks.
No need to explain that. That’s quite obvious but with MSFS, exactly this function doesn’t work anymore since SU10, and I don’t think that Windows is at fault.

My problem is that MSFS freezes when I try to switch back to the MSFS Task in any way, and I have to close it manually via the Task Manager.
That means I cannot use any external apps or paint textures anymore without having to kill the frozen MSFS task and restart MSFS constantly.

Me on Xbox Series X after 3 hours of flight: long freezing, ground surfaces disappearance and CTD with sound effects going regularly in background

I just started getting this today. Alt-Tab to e.g. Edge or Chrome and eventually MSFS locks up i.e. 100% unresponsive. I’ve had it on all flights today after a random time. Last time about 2hrs into the flight. MSFS is just “frozen” but strangely the audio continues.

I’ve been experiencing the same issue for quite some time, and I do have a workaround …

CTL-ALT-DEL and then cancel (go back to Windows). For some reason that “releases” whatever is blocking MSFS.

I wish I knew what was causing this, but at least there’s a workaround (hopefully it works for you as well)
