Looks like you have removed the self-extractor collar.
Screw the bolt & collar back in then use an 8mm Allen/hex to remove the crank. You can expect it to be VERY tight. I use a length of scaffolding on the wrench to get extra leverage.
Refit with a torque wrench.
Edited to avoid looking even more stupid than I am…

Your missing another cap that goes over the crank bolt. That cap would normally force the crank to self extract. They are cheap but it means stopping into a shop or ordering one up. Here https://www.jensonusa.com/sramtruvativ-dub-crank-bolt-extractor-2?section=sfdetails
