Losing France is going to be a huge blow to the Germans, though.Try to negotiate with the Soviets while Germany still has the edge. Launch Blau but only for the purpose of getting the worried Stalin, with his “stand fast” order, to negotiate, and agree to something like Brest litovsk.
Tell Rommel not to attack again in late August and instead pull back into Libya. Shut down type VII construction and try to use the steel etc saved to increase tank, mortar, antitank gun etc production, to stiffen the defensive capabilities of German forces in the east and west. Tell Doenitz to continue with highly renumerative operations like drumbeat and ice bear but more basically obsolete u-boats aren’t worth the investment.
In the West, don’t send reinforcements to Africa when the allies land in force there. Don’t position a lot of forces along the Atlantic wall or in Sicily, but destroy air bases to prevent them falling into allied hands intact. Let the allies enter France but position some forces secretly, if possible, along their route toward the reach and try to shred their logistical tether after the armor passes.
When the allies reach the Geeman border or soon afterwards, launch a massive battle of the bulge counterattack preferably at a time of bad weather, but with forces vastly stronger than in real life (inasmuch as most of the attritional losses of the past two years will have been avoided). If the allied forces are destroyed or severely mauled, just before the ‘44 elections, FDR would probably lose and the Reich may negotiate with the winner, after public support for the war wanes.
Also, given the Allies' demand for unconditional surrender and hatred of Nazi Germany, I don't think that even a mauling is going to be enough to get them to make peace. For them to even consider it, you'd probably have to send the Western Allies back into the sea and completely expel them from every single inch of French territory.
