hello I sketched text and created a boss extrude this creates it well on my 3D but I have an error message that tells me "the update of the sketch text failed"
In my opinion, you used entities such as lines to correctly place your 3 sketch texts, then you deleted these lines, I advise you to use construction lines in your sketch and leave them to do your extrusion/removal of material, I tested on your model and I don't have this error since.
In my sketch I don't see any constraints or sides and to create the text I had created axes but I had to remove them to be able to do the extruded boss
