I got this error while pulling to local. What now? Edited

[jcline871]

I was doing a pull from remote to update my local source tree instance and got this error I've never seen before. Any thoughts on what the risks are if I don't do anything?  What should I do to resolve this?  I have fetched again since and no issues popping up.  Somebody mentioned I may need to remove develop of my source tree and fetch again from remote. If that is the recommendation, how do I delete develop branch off local? The option is greyed out when i right-click on that branch.

I should also mention that I'm not really technical. I do the release process over and over the same way as I was shown. That's it. :)
