The error message that occurs every time I try to create/load a world with a custom dimension is:

at java.base/java.lang.Thread.run(Thread.java:834)The files test1.txt and test2.txt were used to test world creation after loading 1.16 pre1. worldgen_settings_export.json is the file I used to create my Redstone Testing world. I had to manually remove the dimension using an nbt editor in order to be able to get back into that world. I also had to remove the extra dimension's nbt for my survival world too.
The survival world had a caves dimension generation which I used to simulate a cave update for the time being.

It is. I just reported it again because I didn't see this issue. But yes, if you add a custom dimension of any type, it will instantaneously break the world. I was wondering if I was the only one with this issue, but I guess not.
Thank you for your report!
