Do you and your friends try to clear the cache (DDC) to solve some inexplicable problems in daily work

Our development team is just a few months old, and we don’t have a lot of experience with it yet.
My buddy suggested that I try clearing the cache (DDC) if I’m stuck. Occasionally this will work. I don’t like clearing the cache because recompile shader is too time consuming.
I would like to ask about the common cases of clearing the cache.
Thx…
