IOTL the Luftwaffe captured a number of French aircraft and used them as trainers or in some cases stripped them of engines for their own aircraft like the Hs129B:

Even before the A-1s were delivered, the plane was redesigned with the Gnome-Rhône 14M radial engine, which were captured in some number when France fell and continued to be produced under German occupation.

On 27 November 1942, German military units occupied Vichy Air Force bases and seized their aircraft: around 134 Potez 630s of several variants were taken.[22] Of the seized aircraft, 53 were refurbished and dispatched to Romania for use as trainers and target tugs; spare engines were also reused to power a number of Luftwaffe Henschel Hs 129Bs.[22] Production of the type was resumed under German control; significant numbers of aircraft appear to have been pressed into service by the Germans, mostly in liaison and training roles. The last three Potez 631s in service were recaptured examples; these made a final contribution following the cessation of hostilities in their use as trainer aircraft at the Centre d'Essais en Vol for the revived French Air Force.[23]

Still the HS129 wasn't ready for use until 1942!:
B-1s started rolling off the lines in December 1941, but they were delivered at a trickle. In preparation for the new plane, I./SchlG 1 had been formed up in January with Bf 109 E/Bs (fighter-bomber version of Bf 109 E) and Hs 123s, and they were delivered B-0s and every B-1 that was completed. Still, it wasn't until April that 12 B-1s were delivered and the 4th staffel (squadron) became ready for action. They moved to the Eastern Front (to the Crimea) in the middle of May 1942, and in June they received a new weapon, the 30 mm (1.2 in) MK 101 cannon with armor-piercing ammunition in a centerline pod.

Rather than wasting time with the ultimately unsuccessful Hs129B, the Germans had just used captured French aircraft in 1941 and on instead? They already were using the engines, had the air frames, the aircraft weren't as slow as the Hs129B and had decent bomb capacity and range, in fact the Potez 630 was a Bf110 with smaller, less powerful engines in most ways.

Looking at the performance of the Potez 630 it is actually a pretty good aircraft if you've got air superiority, such as the Germans had in most place in the East in 1941-42 where they used ground attack aircraft. Even the French ground attack/dive bomber, the Bre 693, wasn't half bad and no worse than the Ju87 in terms of air survivability: https://en.wikipedia.org/wiki/Breguet_693

It seems remarkably silly that the Luftwaffe didn't take advantage of quality aircraft they didn't have to build, were already using the engines for, and were in fact better than the aircraft they used historically for ground attack missions. In fact they could have freed up resources from having to make Hs129s at all and have the French continue to make their own existing designs. As it was the French continued to make engines for the Germans and ended up making something like 5000 aircraft for the Germans during the occupation, so even with sabotage issues, which didn't stop the Germans from using French production IOTL, they could have had better aircraft for less cost than the crap they made IOTL.

So what if they did this and never made the Hs129? The choice could have been made LONG before they tooled for the Hs129, so they wouldn't have to disrupt production of whatever else they were making, while having existing production lines running in France enough to probably outsource all ground attack aircraft production to. 865 Hs129s were made IOTL and even allowing for the Prototypes in 1940 they'd probably save 855 aircraft worth of engines and raw materials to use on French lines in addition to using what they already captured IOTL. Given that the Me109 was being used as a fighter-bomber and was pretty crappy in that role too, the French aircraft would be a step up in that role as well and free up even more fighters for air superiority missions.
The only shortage potentially would just be pilots.
