Rendering screen crash

[steep island]

Hello. I've had these problems recently and so far I haven't been able to resolve them. They are random crashes mostly a problem with the rendering screen. Google didn't help and only today I noticed that there is an option to ask much more experienced. Thank you in advance for the advice.

It was a private modpack on its own server. Eventually I had to give up. But the crashes didn't have everyone which was even more frustrating.
