How to fix Registry Editor not opening issue in Windows 11, 10

Registry Editor is the tool that we use to fix the error in the Windows system. It is the hub of the registry keys that, when set correctly, fixes most problems. But in very rare cases, the Registry editor can also crash.

Many users have reported seeing the error when trying to search for a key that does not exist on the system. If you try to cancel the search, the app crashes and even if you don’t cancel the search, the app freezes with the following message.

Registry Editor has stopped working.

The root cause of the problem is the length of the subkey. If the length of the subkey is more than 255 bytes, this error is seen. However, sometimes this can also be caused by viruses or malware.
