App Crash Checker
Use this quick diagnostic to narrow down why a Windows app freezes, closes unexpectedly, or will not open.
Before you begin:
Save open work and back up important files. This tool suggests safe troubleshooting steps but does not scan or repair your computer automatically.

What happens most often?
2 Check system pressure ⌄
Open Task Manager with Ctrl + Shift + Esc, then check the Processes tab while the issue occurs.
What is the main resource issue?
3 Test temporary files and app cache ⌄
Close the affected app first. You can open the Windows temporary-files folder by entering the command below in the Run dialog (Windows + R). Delete only files that Windows allows you to delete.
%temp%
After clearing temporary files or the app’s own cache, did anything change?

Try updating the app from its official source. If that does not help, use the app’s repair option or reinstall it. Avoid downloading replacement files from unofficial websites.
What happened after updating, repairing, or reinstalling?
