Can't get non drive side crank arm back on..

I was having some clicking/creaking issues on the bottom of every stroke. It wasn't from pedals nor frame anywhere, I figured it had to be in the bottom bracket or crank arms.
I've never touched these (very new to even having tools to work on the bike), and I've successfully removed the crank arm on the non drive side, and I found a bent washer between the pedal and the bottom bracket. I now can't get the dang arm back on, and I'm not sure I've removed it correctly.

It seems no matter how much I try to align or apply pressure or finesse, I cannot get this thing to even begin to screw back in. The threads on the bracket and the arm do not seem to be warped (yet).

Any advice? There must be an easier way or a trick I'm missing.

I've attached pictures to help make more sense.

Have you tried to put the screw on (without the crank arm) to see if it go in by itself?

I don't know how I'd get the screw removed from the crank arm with it not being held in by anything, and I have nothing else to screw it into

I suspect your self extraction cap (the one with the six indentations) is not screwed in all the way making it impossible for the crank bolt threads to reach the axle.

That's supposed to be there, and it's supposed to be bent. See the "wave spring washer" in step 7 of the instructions desertdork linked.

And I'm not saying it's definitely the cause in this case, but there have been complaints of creaking on BB30 setups at the bearing-to-frame interface. You'd need special tools to get those bearings removed and replaced to address the problem. I'm all for DIY in general, but unless you want to invest in a bearing removal tool and press, this may be one of those jobs your local bike shop is better equipped to handle.

Thank you that makes sense. I'll see if I can manage to get the crank on with some help from someone to keep things tight for me, so that I can ride this weekend, and probably take it into the shop Monday. Getting that dang crank arm back on is frustrating.
