Warframe crashes randomly, haven't been able to get past the first area

I have searched google and these forums for similar problems, sadly to no avail. The game will just quit and I lose all of my progress. Because of this, I haven’t been able to get past the first tutorial area (the one where you run away from Vor). It has made it slightly farther every time so far. I suppose it could be that it is running out of memory, but I did change the “Texture Memory” option to high. Otherwise, the game runs at an unstable 25 fps, though I am unsurprised by that as I haven’t gotten a dedicated GPU yet. Is there a way to increase the amount of RAM Lutris can use? That could be the problem.

EDIT: Tested again, it didn’t make it as far as last time

EDIT 2: Error message:

EDIT 3: Forgot that this was the Lutris forum and not Warframe. Changed “Game” in the title to “Warframe”
