Player clipping through blocks

[MochiBingo]

Describe the Bug

I made an elevator that closes a gate and then starts lowering, but the gate is buggy and has some visual problems, but almost every time I stand on the elevator, when it starts moving it turns invisible temporarily and I clip through the floor, and it usually takes a few extra seconds to come back to visible.

Reproduction Steps

I stand on the elevator, press the button, wait for the gate, and then I clip through the floor once the elevator starts moving.

Expected Result

I expected to not clip through the elevator, i have a smaller create contraption in my base and I don't clip through that.

Additional Context

I looked at it online and it seemed to be just a rendering issue, but I don't have any of the problem mods installed.
