Describe your problem, including steps to reproduce it:

It happened when I tried to use the elevator (when I pressed the control button) on pneumaticcraft.
The elevator was working normally, but suddenly the minecraft crash and now I can't play in the world that it happened.

Any other comments?

(I'm using google translator to write this text)

Here is the report of when the crash happened for the first time:
crash-2020-03-30_23.14.36-client.txt

And here is the report of when I try to access the world:
crash-2020-03-30_23.29.45-client.txt

The mod in the stacktrace is Better Portals, by the way (de.johni0702.minecraft.view.impl.client.render.ViewRenderPlan.renderSelf)

Doesn't mean it's necessarily that mod's fault, but I'd check with them (https://github.com/Johni0702/BetterPortals/issues)

That has nothing to do with PneumaticCraft elevators. Don't know what mod that stack trace is from, but not this one for sure.
