i wonder why the 1.11.2 version will not work once the 1.19.2 chunks have already been loaded
its bc 1.11.2 doesnt know 1.19.2 minecraft yet, so it doesnt know what to do, regenerating then erroring each chunk that you've rendered (if you've rendered a lot, say goodbye to your server (unless you reset it)) so yeah also why 1.11.2
