Can't play game after moving off of external hard drive

Hello, I recently downloaded Dragon Age: Veilguard onto my external hard drive because I did not have space for it on my internal hard drive. The connection to my external hard drive was not great, so I was experiencing some lag. I made space on my internal hard drive and moved the Veilguard game folder to the EA Games folder along with all of my other installed games. The EA app says I do not have the game installed, and says as much when I double click on the .exe file directly. There is no option to manage the properties or repair the game like there are with the other games I have installed. I tried changing the default install location in the settings, uninstalling and reinstalling the EA app and using the App Recovery tool, to no avail. I have seen suggestions to start downloading the game again and picking the location of the installed program. The problem is DA:V is a whopping 91GB download, and it won't let me begin the download without making space for it, which I am unable to do. Is there a way to go in and fix the installation files, or am I forced to delete and reinstall? My internet connection is spotty at best, and the EA app will often stop downloading without resuming once it is back online. So I come back after stepping away from my computer minutes or hours later to find I have made no progress on the download. I'd rather not have to take another three to four days to re-download such a large file if possible.
