This won’t help much, and I don’t have the publisher so I don’t know.
But knowing blender, it may not be you entering texture mode, or creating the executable, but if your trying to open a corrupted Jpeg, or something strange like that. If you have a few scenes with a copied object that has no faces. (that was just a made up example of the sort of things that can cause these problems)
Try a basic scene, check it in texture mode, check the executable, do they work? If yes, build on it a bit, and so on, until you find what eventually causes the crash.
If it simply crashes from you performing the action of entering texture mode, it could be a hardware/software conflict, as Not everyone is shouting out about this problem. (i don’t think). And your best bet is to wait for 2.26 (if ever!) or re-install 2.25
hope this could be of some help
