Same thing happened to me and it looks like you bent your bracket too just like me..
BE VERY CAREFUL WITH WHAT NEEDS TO BE DONE.... It's simple.. but can go VERY wrong if you are not careful..
1. Look at your picture. You can clearly see where the lower bolt is just in the bracket, but should be going into the engine block as well. The head is just stuck there, the rest is still in the block. You can also see, that for that bolt to reach, that bracket needs to be bent back into shape.
2. Remove the Kickstand. It's just that one bit bolt now. DO NOT use the kickstand for leverage... Removing the stand from the bracket. If you have access to a table vice, you can bend this bracket back to a 90 degree angle. Do it slowly. Use a square to check for.... squareness.. If it breaks, it breaks and you're no worse off... but it should bend, it's kinda designed to. ( I should mention a disclaimer here I guess... MINE didn't break, I was able to bend it just fine). If you have a metal shop around and they can make it true again for a few bucks... do it.)
3. CAREFULLY remove the rest of the lower bolt that is still screwed into the block. There are lots of methods... my tact was to drill a tiny pilot hole into the bolt just large enough for my smallest Easy-Out to get in a grab it.
4. You don't want to damage the threads as there is not a lot to work with to re-tap it or heli-coil it... so you want to avoid that if possible.
5. Once the old bolt remnants are removed, hand fit your bracket back on making sure you bent it back into perfect shape so it sets flush on the engine and DO NOT FORGET THE LOWER SPACER. There is a spacer on the lower section between the bracket and the engine. As yours is missing, you'll have to measure and replace. You might use the bolts and adjust them finger tight to ensure perfect fit. I guess this is the point where I mention... you need to buy a new lower bolt. I forget what size it is, but you'll have the old one to take to the hardware store once you get it out... and you'll need that spacer too..
6. Put it all back together.
FWIW... A Sport Chock is a great thing to have. Just drive the bike on it, and it's upright. I only use my kickstand when I'm away from home, my bike it always in the chock. Kinda fun to just drive in and hop off.
