Hello ,
I’m here to help you in resolving your issue
Since you're seeing flickering focus and even Explorer.exe showing up in focus logs, it’s likely something running in the background is stealing focus briefly, then returning it , just enough to cause input drops without visible windows.
Disable Background Apps & Services (Clean Boot)
Run a clean boot to rule out third-party programs:
- Press Win + R > type msconfig
- Go to Services tab > check “Hide all Microsoft services” > click Disable all
- Go to Startup tab > open Task Manager > Disable everything
- Reboot.
Try running your game or app again. If the issue is gone, something from startup is the culprit.
After trying above steps, please reach out to me if you have any doubts or issues
