Installed apps refuse to be uninstalled/pc can’t find them

I’m trying to loosen up storage on my pc, and these two huge apps are taking up space, but I can’t delete them?? It’s Riot Client, and Escape from Tarkov battlestate games, both of which I haven’t used in forever and thought I had deleted. When I go into my windows settings to uninstall them, I get hit with “Windows cannot find ‘C:\Battlestate Games\EFT\uninstall.exe.” And asks me to make sure I typed the name in correctly, I can’t find these files anywhere, and I don’t know if it’s even taking up space, or is a glitch, but it says that they’re both taking up 60GB together
