I would check the belt paths. Are they all sitting correctly in the idlers?

Can you post a video of you moving the gantry back and forth and then moving the EVA carriage left and right?

Yeah I'm seeing a lot of vertical movement. It's hard to see the idlers in the printed part but the pulley looks to be a little low
I'd highly recommend the fmmm mod down the line. For now can you try to take a close up shot of the idler stacks? You will probably need to remove the top printed part for the motor mounts unfortunately

Your frame is likely square and not the issue. I'm thinking that at some point your idlers are not matching in height and my guess is that's between the motors themselves. When you can take pictures of all the idler stacks including the xy joiners and front idlers

It looks like the top belt from the left motor is going to the bottom idlers of the right motor.

From what I can see your idler stacks look good
That's normal I think
Mine does the same thing

Are you sure your motor pulleys are at the correct height? If I rember correctly, the mm numbers are wrong in the documentation. On the right motor, is the motor shaft flush with the top of the pulley or is the shaft a little longer?

hmm, then it seems to be right. I remember though I had to put both pulleys (I think) a mm lower than in the documentation.
