That is hard to prove contrafactual. The Germany still lost WWI which was massive sticking points for them. The "stab in the back" myth would existed either way, because Germany being having super militarized culture could not admit loss.

The revolution in Bavaria would still happened. And still irk right wing. The democracy would still be rejected and Weimar Republic would still be one massive mess.

Hitler did not gained power just because of social issues.

(And also, less importantly, had Germany won the WWI, they had plans to ask other countries for large reparations. It is not like those were something unheard of at that time.)
