KSP keeps crashing after I activate my NERVA engine stage

[Bendy Snowball]

Hello!

I was trying to develop and test my new interplanetary rocket and ran into a slight issue.

For some reason whenever I try to activate my NERVA engine on my rocket everything disappears and the game crashes
By disappear I mean if I am looking at Kerbin while in orbit, and then I activate the engine every just disappears, the only thing I can see is the skybox, and the game crashes.

Any ideas?

Also, here is the link to my KSP.log file

My log file starts when I unpause the game and activate my NERVA engine, which then causes my game to crash as seen in the rest of the log file.

I see two errors being spammed in the logs:

[WRN 00:24:29.876] [KSPI]: realIsp is NaN

[WRN 00:24:29.876] [KSPI]: finalThrust is NaN

[WRN 00:24:29.876] Attempt to set pitch to infinite value from script ignored!

This looks like KSPIE doing something wrong and is probably the root cause.

There's also this repeated several times every few milliseconds:

[ERR 00:24:29.869] Screen position out of view frustum (screen pos 0.000000, 1440.000000, 750000.000000) (Camera rect 0 0 2560 1440)

It would really help if you added the KSP version and mod list.
