I apologize, I didn't know about the luncher_log file.
I updated the report and added the file.

Wow, three crashes in one run...
At least the third and fatal one is MC-130088

Ok, that were two crashes, a non-fatal and a fatal. I've split off second one since it's already in an own ticket.

Please check if that's still an issue for you in 1.13.1.
Without logs ?
There is always a log:
Please add the file
[.minecraft/launcher_log.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]
to this ticket.
