Hello Valve team,

I’ve literally tried everything on the planet to fix this, and the issue is still happening:

Windows 11 Pro is activated and fully updated

Latest NVIDIA drivers installed (RTX 3070)

Verified game files multiple times

Tried both Fullscreen and Borderless Windowed

Disabled Steam, Discord, GeForce overlays

Tried -dx11, -vulkan, -novid, FPS cap, and other launch options

Disabled fullscreen optimizations, forced high-performance GPU

Even tweaked NVIDIA Control Panel settings

Result: Dota 2 still crashes consistently when I alt-tab, no matter what settings I use.

Since many other players are reporting the exact same problem, this looks like a core client bug, not a system issue. Please acknowledge and fix this in the next patch — it makes the game unplayable for anyone who needs to alt-tab.

Thanks.
