Supposin' Hitler dies after the Munich conference but before invading Poland and starting WW2. Assume also that some kind of Nazi government continues after the inevitable power struggle AND that somehow the economy limps along just long enough to recover from the effects of Hitler's policies. Whoever takes over realizes France and Britain will move if Poland is attacked, so he holds off. Germany has Austria and Czechia to digest, anyway. Poland gets a reprieve. In short, Nazi Germany survives. Perhaps not the most plausible outcome of Hitler's early death, but let's roll with it, shall we?
So... Then what? There's no war in Poland, no Barbarossa, no Holocaust. Where does the world go in such a scenario? What's the likely long term position of the Czechs in the Protectorate? Does it get fully annexed, giving the Reich a new, large and restive minority? Nominal autonomy? Nominal independence? How long can the tense peace last before someone invades someone else?
What do you, the readers at home, think?
Let's say for the sake of argument that Hitler's death by natural causes comes between the Munich Conference and the violation of the Munich Agreement in March 1939. Goering likely takes power due to his stature relative to all the other Nazis and the inability of the anti-Nazi conspirators to regroup quickly enough to stop him from reaching power, especially as he would have a lot of public support and support within the party and military establishment as well as internationally (he was seen as the 'reasonable Nazi). Goering doesn't do the aggressive Hitler moves of OTL because he doesn't feel he has the power yet that Hitler did after Munich. Munich was Hitler's coup, not Goering's, so Goering would have to take time to build up his national and institutional support to make any other moves internationally. First though the issue of rearmament would have to be addressed, because it was unaffordable and there were other options that he would have to take to address this financial issue that Schacht was proposing. Assuming he was doing what he did IOTL to stay in Hitler's good graces and amass power relative to his rivals by appealing to Hitler's desires, Goering in power would have been somewhat of a different animal. According to a biography I've read on him, he was seriously opposed to going to war in 1939 and hated Ribbentrop for pushing that option and convincing Hitler that was the best way to go. So being smart and informed enough about the state of the economy, as he ran most of it, he'd likely recognize that continued rearmament would push the nation into war if he didn't wean the economy off of it, as Schacht was urging, as they'd have to smash and grab to keep the economy moving if they just continued to rearm. Given that Goering still have a lot of good will in Britain after Munich but before the violation of the agreement, getting bridge loans to transition off of rearmament would certainly be possible, as Chamberlain, already riding high after the Munich Agreement, would be able to say his diplomacy was such that he managed to get the Germans to stop rearming and avoid the path to future conflict, as well as solidifying the perception that Munich was a viable agreement.
The problem is that the international economy was still pretty messed up. The German economy was effectively running on debt it had been racking up in trade deals that screwed Germany's suppliers of raw materials. Likely a Goering led Germany would be forced to look for increased barter deals with China to get access to raw materials at a discount, which means screwing Japan by trying to find ways to blunt their military adventure in China to maintain that trade. It will probably also mean working with Poland and Russia to get trade deals, as well as increasing market leverage in the Balkans. Just because war is avoided over Poland doesn't mean the economic situation is going to be great, especially as the Nazi vampire economy was not really set up to generate peacetime wealth. They'd probably have to let Schacht run his program to find foreign suppliers of raw materials to enable the German economy to work, while ruthlessly hunting down arms contracts to make money.
This book details the scheme that Schacht was developing pre-war, but was derailed by Hitler in his bid for rearmament before jumping into war:

That would be the one path really open to the Nazi government without war.
I think that there is a path that could be charted that wouldn't result in war, but I don't think it would be particularly prosperous until free trade in Europe became more of the orthodoxy. At very least though the Germans would have to sign some sort of trade with with the USSR like they did in 1939-41 and pay up to keep their economy running without war. Stalin wasn't looking for war to expand his empire, he was just interested in building up the USSR to ensure 'Socialism in One Country' worked.
