Screw went through my tire and rim bed this morning. Sent a request in to canyon about repair/replacement.
Was considering sanding, putting rim tape over, and running with a tube in the meantime. I’m not enough of a carbon guy to determine if that’s a “good enough” temporary limp solution. Thoughts?

It’s your collarbone buddy.
What does the area around the puncture look like? It might be okay, but I know I cant see anything other that blemished rim tape. Yank that stuff off and really look. Last thing you want is a failure when you thought it was good enough.
I’d probably fill it with resin, run a tube and send it… But this is not advice, I’m just crazy.
Edit after seeing the tape-off photo: still no.
Punctured carbon = cracked and delaminated carbon, and wheels flex a lot with use. This will only further delaminate over time. If used, it’ll fail at some point, and that photo with the tape off shows a lot of fraying. Your plan might have worked if you had accidentally run over a perfectly positioned drill press, but that rim bed will only continue to work itself apart.
The average road wheel rotates about 750 times per mile with subtle flex with each rotation. That’s a lot of compounding forces at play.
Safe answer = no. Mileage will vary with other recommendations.
Dangeous to ride. Not because the carbon itself, but the hole its enough big to damage a inner tube with the pressure. Maybe you can ride a little bit with low pressure but know that while riding the pressure inside rise cause the temperature increase with the rolling resistance and the sun.
The damage look repairable, look for a carbon fiber expert.
You can theoretically run a room that is in as many pieces as you have spokes. That doesn’t mean it would be a good idea to do that, mind you. And that logic applies to steel and aluminum rims. Personally, I don’t think carbon works the same way. I wouldn’t chance it.

This is why dentists can afford such bikes.
