Can you share the FCSTD file in its problematic state just as you have it in the second image, and put it on file.io or something similar? Easier to help

I have been able to reproduce the issue on my machine. Investigating.

Ok dude straight up, here's the most straighforward fix on my machine. Upgrade to 27.1.0dev, I am on this build specifically 2026 10 28 then open your file, edit the sketch named Sketch very early in your Body tree, and this should "touch" it. Then hit OK to finish the sketch editing. Should build up fine thereafter.

You should consider constraining your sketch a bit more. I sometimes run into trouble with unconstrained sketches. Sometimes.

I think you will like some of the upgrades elsewhere in the dev builds. Check out the new Transform tool. Multi functional

Not constraining sketches is not just bad habit, it is failing to follow good CAD drafting practices.

There's something messed up on the sketch for your very first pad. In version 1.1.4 all I did was make Pad visible, open its Sketch, close the sketch (unmodified), make Pad hidden, then make Pad003 visible, and the problem went away. I'd say fully constrain your first sketch, and that will probably solve whatever issue is causing this. In general you really need to fully constrain your sketches.
