Sims 4 won't download on LaCie external SSD 2 TB

Hi all,

I haven't played Sims 4 in over a year, now that I have an external SSD with 2TB of free space (Lacie Rugged Mini), I'm eager to install it again on my Mac (Catalina 10.15.7).

I have made a symlink successfully and I have been able to start the downloading process. However, halfway through this notification appears that my SSD has run out of space to continue downloading. I checked my internal HD and saw I'd run out of space there as well (11 GB free)... So, I deleted the download. If anyone could help me out, I'd very much appreciate it!

I hadn't used up any space before attempting the Sims 4 download. The 11GB of used storage on the SSD (on the image) is supposedly because of the download.... I did eject the SSD properly  then disconnected the USB-C from my Mac and plugged it back in, to solve this particular issue... The storage problem is still visible, however.

Thanks in advance!
