So I recently got a new wheel and I can't get the cassette lock ring on if this plastic washer is still inside the cassette. Can I ride without it?

Depends. It’s for a hyperglide cassette / hub where the hub is a bit longer than the cassette.
So, if you install the cassette and snug the ring and it’s not tight, then yes.
I’ve currently got the opposite problem – a cassette that’s too long for the hub body.
One is HG a road and one is HG a mtb… slightly different lengths, this makes up that length.
That’s a cog spacer, it goes between the cogs of an 11 speed cassette, it’s not the type of spacer that goes behind the cassette.
Are you trying to use an 11 speed cassette on a 10 speed freehub by any chance? And no you can not leave this spacer out.
Later you will but today we ride
That is a cog spacer. Make sure all the cogs are equally separated.
As mmlow has already said, this is a spacer which goes between sprockets on an 11speed cassette. If you were to leave it out then there would be no gap between two of the sprockets, so yes you definitely need to include this item in your cassette installation. If you can’t get the lockring on you may need to discard the spacer which goes on the freehub behind the cassette. Also/or, have you cleaned your cassette before installing it onto the new wheel? I only ask because, a couple of years ago, one of my friends came round with a new rear wheel and said he was unable to fit his old cassette to it because he was unable get the lockring to engage. Turned out it was just because he hadn’t cleaned his cassette and the small amount of dirt on the interface between each sprocket significantly increased the overall thickness of the cassette!
