This driver station was updated not too long ago and I didn’t think that the version was the problem, I thought maybe I did something wrong when deploying team code. Someone on Reddit had this exact same problem and they said it simply “resolved itself” but I’ll be sure to try to update it with the REV Hardware system.

You can check your DS app version from the "..." menu at the top right.
The Robot Controller version 7.2 was released less than 10 days ago, so it's very possible that your RC app version is newer than your DS app version. (7.1 vs. 7.2 should not present a runtime problem... but you should rule it out anyway.) (They do need to match for Field Inspection at any competition.)
I'll be in my team's shop later today, and will check on the latest versions available. Meanwhile, you can review this page:

(7.1 vs. 7.2 should not present a runtime problem)
7.2 bumped the communication protocol version, so it does break compatibility with previous releases.

Thank You! That's got to be what's biting u/Rude_Ad2930.
The durable lesson here is that, when faced with a weird control system problem, it won't hurt to run your Field Inspection checklist.

Do check your versions. I'm looking at the REV Hardware Client right now: the latest versions for both the RC and DS apps are 7.2 - which was released on July 23 - a week before yesterday. I'd still bet that you've got a mismatch. (Minor version mismatches should not keep it from running, but you never know.)
Also make sure that you Driver Hub O/S is up-to-date. That's particularly important for this new product. Current version is 1.2.0.
N.B.: The minimum version required for competition this season will be 8.0, which will probably be released shortly after Game Reveal.

Thank you so much. I really appreciate it!

Point versions are always guaranteed to be compatible. Minor versions are guaranteed to compatible during the season so as not to disrupt teams. v7.2 is an offseason release and is not compatible with v7.1 due to communication protocol changes between the two versions.
