To be specific, I'm in Version 6.1.97 r150532 (Qt5.15.2) for some reason, and the solutions I found on the Internet are about installing VBoxdrv, unfortunately, there wasn't a folder for it, and when I attempted to install the vboxdrv.inf file, it was asking for vboxdrv.svc file. There was a VBoxSAP folder, installed it, ran the command to start it, then it said it didn't have the correct signature. Starting both* of my machines showed this error, but it wasn't there last night.
*Windows Vista and Windows ME, but Windows ME isn't installed yet, I got the error when I tried to start it in order to install it.
