Can't run Doom Eternal because it "Failed to allocate video memory"

I bought an external SSD just for this because my computer has very little storage, not nearly enough to run Doom Eternal.

It crashes every time I try to open it with the same message, "Failed to allocate video memory" I have no clue what this means or how to fix it, I cant find anything helpful online.

I've spent a lot of money on this, help would be appreciated.
