Cura 4.6.1 won't see my Ender 3

[Skogula 0]

I can connect perfectly fine using Pronterface or S3D, but nothing I have been able to do has allowed Cura to even see the printer. It doesn't even give me anywhere to select a com port or baud rate. Any idea what is up?

That's weird. Can you share a log?

Here is the log, backed up the old one and let it create a new one for this instance only to cut down on clutter. 
Everything else does detect it on Com 7.

Are there any other devices that might be interfering on that COM port? Or is it possible your printer's board has been damaged somehow? Some clues are in your log:

I can't think of anything that would be interfering. And as I said, it connects fine to Simplify3D and Pronterface, so I don't think there would be damage since they should all be using the same connection protocols. That is what had me stumped.
