How am I supposed to resolve a red sketch with no errors indicated? I know, it's a simple sketch and I can just delete everything and fix it. But what if it were a critical and complicated sketch?
I'd start by displaying your sketch relations as this will give you a better idea as to which relations are causing the issue. Furthermore, you can switch the dropdown from "All in this sketch" to "Overdefining/Not Solved" to highlight any such relations. Finally, you can upload the part file here for further insight from others.
That's what is shown in the attached image. As you can see, there is nothing shown as overdefining, nothing not solved.
I meant show the sketch relations visually (i.e. View->Hide/Show->Sketch Relations + Sketch Dimensions). Do you get any errors from the "Repair Sketch" dialog?
Also, how did you create the sketch? I.e. the center rectangle, four lines and a centerline, etc.? We may gain insight if we see that this arises from one method over another. Can you upload the part file?
Sketch dimensions are already turned on. I did not run Repair Sketch. I created the sketch long ago, using a center rectangle. The model was fine for months, then it wasn't. Been seeing a lot of that with 2019. I guess they added an auto-break-sketch function.
I wish I could upload the model, but cannot.
Thanks for your suggestions.
Do you not have access to the part any longer? Sketch relations is not shown, otherwise we could associate which relation is on which part of the center rectangle. Otherwise all we can do is guess and that only gets one so far. I'd want to know how the bottom and right edge is fully defined. It looks like the two Collinear relations are external, so I guess something external to this sketch was updated, and now the relations you have in this sketch can no longer be solved (e.g. something external to this sketch is no longer horizontal or vertical).
Can you recreate this error repeatably enough to make a new part with this error?

I've heard about that! I had been waiting for it to debut for years!
Yes, I have access to the part, but I had to fix it. The work's got to get done.
Interesting that display sketch relations was turned off. It wasn't the day before.
Is the Midpoint2 relation overdefined? From the screenshot Midpoint2 is highlighted, and Solidworks only seems to have one color for highlighting, so it could be the Midpoint2 relation that is causing the overdefine error (red lines in sketch). Can you either highlight another relation to check if Midpoint2 is red underneath, or switch the dropdown to "Overdefining/Not Solved" to verify this is/is not the case?
No, I just moved the cursor down to verify that the first constraint was not broken. Midpoint2 was okay.
And overdefining/not solved was blank.
Sketch Expert tool?
That's a good thought. Unfortunately, it still doesn't tell me where the problem is.
Looking at the sketch, I would guess that both of the Collinear relations are conflicting with one of the horizontal & vertical relations. Can you suppress each one in turn & see when it the errors go away.
Have you recently turned on the "Verification on rebuild" option in settings recently for SolidWorks to suddenly start throwing up an error?
I didn't change any settings. Verification on rebuild has always been on.
The problem is not that I don't know how to fix the sketch. It's that SW keeps breaking things out of the blue (2018 did not do this to me) and doesn't tell me what is wrong.
Thanks for your advise.
Delete the Collinear relations and re-attached.
I would just kill the external references, that or make the dims driven.
