I am experiencing crashes on my Minecraft 1.12.2 Forge. It usually crashes when I try to join my world. The reason is Ticking Player. I don't know how to solve it.

 

Here's the crash report:

If anyone could help me, I'd greatly appreciate it.

I have 12 mods in my "mods" folder, but none of them is a bug/virus etc. because I have allready played normaly with them all. Please help me.

This seems to be an issue of the immersiverailroading. Try reporting it to the mod author

1.12 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.
