App Crash Troubleshooter™

When an app keeps crashing this tool finds the exact fix
When an app keeps crashing, the error report is not helping you. Error codes like 0xc0000005 and EXC_CRASH (SIGTRAP) are written for engineers, not people who just want their app to work. This free tool translates both into plain English and gives you the exact steps to fix your specific crash — not a generic list of things to try.

Two ways in depending on what you have
Not everyone opens a crash report. Most people just know their app keeps crashing and they want it to stop. This tool has two paths built into the same tool. If you have an error code, find it in the decoder. It translates immediately into what it means, why it happened, and the specific fix. All ten codes are verified for Windows 11 26H2 and macOS Tahoe 26.5.1 in 2026. If you do not have a code, pick your symptom instead. App keeps crashing every time you open it. Crashed after a Windows or macOS update. Freezes and stops responding. Out of memory errors on Mac. Multiple apps crashing at once. Each one routes you to a different fix because each one has a different cause.

The 2026 bugs that affected a huge number of users
Windows 11 update KB5074109, released January 2026, caused apps to freeze when saving to cloud storage. Microsoft confirmed this. On macOS Tahoe, Microsoft 365 apps including Outlook have been crashing on calendar events since June 2026 with error signature EXC_CRASH (SIGTRAP). Both are covered with the specific fix, not a generic restart suggestion.

Mac users on Tahoe get specific help
macOS Tahoe changed how memory is managed and reserves resources for AI and security tasks, leaving less available for other apps. Macs with 8GB RAM are the most affected. The tool covers the memory error, the silent quit unexpectedly crash, kernel panics triggered by Tahoe’s tightened SIP rules, and the SIGKILL terminations hitting Safari, Photoshop, and Firefox. Each one has its own fix because none of them are the same problem. If your app keeps crashing after a Tahoe update, start with the Mac section.

Still seeing app keeps crashing after trying the fix?
If you have worked through the tool and the app is still going down, you are usually dealing with a driver conflict, a corrupted system file, or a hardware fault the app is not reporting. Our Remote IT Support handles it remotely in one session with no callout fee. You can also browse the rest of our free tech checks while you are here.
