Explorer.exe crashes when right-clicking a specific file type
Every time I right-click on a specific file type in Windows 11 File Explorer, Explorer.exe crashes and restarts instantly, with no error message or warning, and this only happens with that one file extension while all other files work perfectly fine when right-clicked. I've already tried running SFC scannow, DISM restore health, and cleared the thumbnail cache, but nothing has fixed the issue, and I suspect it might be caused by a problematic context menu handler or third-party shell extension tied to that file type, so I'm looking for a way to identify and disable the specific culprit without having to reset my entire system.

The most efficient way to identify and disable the culprit without resetting your system is using a free tool called ShellExView.
Hi, your suspicion is right: when Explorer only crashes on one file extension during right-click, a shell extension or context-menu handler is one of the first things I would check.
Open Event Viewer > Windows Logs > Application and look for the Explorer crash. The faulting module can sometimes point straight at the vendor DLL. If not, use a tool like Sysinternals Autoruns or NirSoft ShellExView to disable non-Microsoft context menu handlers for that file type, then re-enable them one at a time until the crash returns.
I would also check the default app association for that extension. Sometimes the broken handler belongs to an app that was partially removed or updated badly. This approach should let you isolate the culprit without resetting Windows.
