I'm not sure if 26002 is the minimum affected version because I'm already on 26016. The earliest bug report here is #2030 and it says 26002 is affected.

Good investigative work!

From what I understand Microsoft is trying to change the desktop implementation in the recent insider builds.
The changes may end up being different or never reach the final stable build, so checking version may not be a good idea:
Environment.OSVersion.Version.Build >= 26002

What if the first search fails we check for progman child Window as a fallback or something like that?

I don't have insider build with me at the moment, things to verify with this fix:

1. Does wallpaper input (mouse/keyboard) still work.
2. Does opening chatgpt, taskview and app switcher crash the wallpaper.
3. Does the wallpaper pause algorithms still work properly.
4. Does the wallpaper restore properly when explorer/workerw crash.

1. Does wallpaper input (mouse/keyboard) still work.
   mouse and keyboard work properly
2. Does opening chatgpt, taskview and app switcher crash the wallpaper.
   taskview and app switcher do not crash the wallpaper. copilot is not available in my country so I cannot verify if it really works. but at least the copilot sidebar saying it is not available can show properly and the wallpaper does not crash.
3. Does the wallpaper pause algorithms still work properly.
   I haven't checked every combination of these settings, but I think it can work properly.
4. Does the wallpaper restore properly when explorer/workerw crash.
   the wallpaper restore properly after I kill explorer.exe and relaunch it
