Component Exception Error -Please help :(

I got this message today on file I am working for months :
Component Exception

An exception was thrown during solution:

C_UUID:15571c5b-4c9c-484e- bb0b-61625b473022

etc…

How can I fix this?
Can I just somehow find the element and delete which became corrupted?
