Dropouts are badly misaligned, can a torque arm (or threee) fix or am I a fool for even considering keeping this frame?

So I sarted my e bike build a few days ago. I've ridden it a little bit here and there, on max throttle and putting a lot of torque through (I was going to install torque arms anyway, but was going to do that this weekend, maybe I was an idiot for not doing it at the same time as installation), and no issues with the wheel. Anyway, now I notice that the dropouts are badly misaligned and the wheel barely slots into one side. See below:
38891

I have done a very short test run just to see how easily it pops out like this, and the answer is, well: very. Soon as I give it some oomph there goes the wheel.

I have no idea how this has happened... haven't crashed the thing, so I'm really confused to be honest.

My question is: is this salvagable. The frame is aluminium so I have no hope of bending it back. Only option I could see would be to use a torque arm, and probably at least 2 that side and 1 the other side to be safe. Would this be sufficient, or would it still be risky given how little the wheel is sitting in the dropout?

Also, what torque arms would be best for this bike? This style seem to be by far the most popular to buy online, I didn't know if it was because they were best or just cheapest/most universal.
I'll be very sad if I have to just scrap this frame but I'd rather do that and start again with new frame if it really is doomed to just fail pretty soon even with the aid of torque arms. Any help appreciated cheers.

Lossen the opposite side and see how the axle sits both sides and the wheel within the points of the drop out. The wheel torque shouldn't cause the frame to twist unless it is/was already cracked or damaged.
Tbh just looking at that pic I would say the axle isn't sitting deep enough in the first place.

You didn't tell us which motor and controller you have!

Whatever you do, you'll need to file the drop-outs so that the motor goes in properly.
