Just to add here, a fix is to disable MPO, an easy way is shown here by nvidia https://nvidia.custhelp.com/app/answers/detail/a_id/5157/~/after-updating-to-nvidia-game-ready-driver-461.09-or-newer%2C-some-desktop-apps
here’s some other threads of it working for others, but ofc do your own research if you’re unsure
but as others have said, it is a windows issue, version 24h2 specifically, and has been acknowledged by windows, but is yet to be fixed in a public build
https://blogs.windows.com/windows-insider/2025/01/29/announcing-windows-11-insider-preview-build-27783-canary-channel/ as can be seen here,
Fixed an underlying issue which could lead to unexpected app window freezes for some people when using ALT + Tab between certain types of apps.
so hopefully they push it into an actual public build at some point, but yeah, it’s a windows issue
