Any chain drop solutions on the CCX?

Yeah, me too. I'm guessing that guard wouldn't allow it because of the design. The OEM doesn't taper in like that.
It doesn't get jammed, but yeah it can fall in that small space. If I downshift and keep pedaling it will pop back on the ring though. Thinking about it more it's not really a chain guard since it lets the chain fall off. It's more of a chain ring guard so you don't get your pants greasy.
That's why I advocate the narrow wide solution as it's specifically designed to address chain drop on 1x drivetrains whereas a chainguard is more to protect the teeth from impacts, but as a side affect can help keep the chain from jumping off if the gap between it & the ring is small enough. The stock chainguard did help keep the chain from falling off for a time on that one side but eventually it would just wedge itself in the gap.
I inspected further and I don't think my CCS can fit a double guard anyways. They chain stay is just too close (pics attached). However there looks to be enough room to fit a double sided change guide so I bought one on Amazon and will let you know the results. I also found the Deckas 130BCD on Aliexpress for $20 so I ordered that but won't be here in a long time.
Just in case I bought a new chain too. Mine has well over 2k miles and not sure how long these last on E-bikes.

The gap on my Cross Current looked like the one in your picture. I removed the chainring guard, flipped it 180 degrees, and reinstalled it. It’s pretty easy to do and it reduces the gap enough that I have not had any issues with the chain coming off to the outside (which used to happen all the time).

It didn't even cross my mind that the guard wouldn't be perfectly flat. Good thinking!
I put on the double sided chain guard ($25) last night and no drops on the ride in this morning. Anyways it looks like there are quite a few solutions posted in this thread.

Just the allen wrench and a chaining nut tool. No need to remove crank. If you're lucky you might not need the chainring nut tool (if you can loosen the chainring bolt without the nut spinning on you) or you might trying improvising with a large flat screwdriver.
I did put a bit of grease on the threads.
A thanks-in-advance for this thread/info - I've ordered a Deckas 130BCD narrow/wide for $20 off AliExpress. Started to get more routine drop drops recently, where they used to be more rare. Less than 1k miles, so I doubt my chain has stretched much, more likely related to the street work going on now. I'll probably go with a slightly shorter chain when I replace it, but for now I'm looking forward to a reduction in drops based on the chainring. This is on a 48v CCS.

Timpo, I think you've got it wrong. The whole point is to get a narrow-wide chainring. With the Deckas one that has already been talked about, you only replace the chainring, and can re-use everything else. No new bolts, guard, etc needed.
Also, you don't need a chainring tool. I thought I needed one, but you can do it with just the correct allen/hex wrench.
