Cannot install OR uninstall game

[CoffeeCup]

Hey so I'm having a weird issue. I'm trying to uninstall Remnant 2 because it got stuck on some weird verifying cache loop, so I wanted to restart it from scratch. I tried uninstalling it, but it just never worked, no matter how long I left it. When I restarted my computer to see if that'd fix it, whenever I launch Steam, it says it's Installing Remnant 2, but it's not... doing anything? When I look in the folder all I see is pakchunk0-Windows.ucas 41.3 gb file.
I tried deleting the Remnant 2 folder off my system, but whenever I launch Steam it just puts that huge-ass file back there and continues to do absolutely nothing - it doesn't even let me uninstall it to wipe the slate clean. Any advice?
I tried Uninstalling the game again, but it just says "can't uninstall - Busy" no matter how long I leave it.

Found an answer.
Basically I killed Steam in Task Manager
Then I unplugged my whole internet.
I deleted the Remnant 2 folder.
Then I opened Steam, WITHOUT INTERNET CONNECTION.
Deleted Remnant 2 from Steam there, as well
Exited Steam
Reconnected Internet
Restarted Steam
Now it's downloading normally again.
