server crashing for unknown reason

.minecraft mod list

aternos mod list

for some reason the server keeps crashing. The crash report will be shown below. i got all the mods necessary, including otg and biome bundle. versions match my launcher versions.

yea, i cant make a world in minecraft and upload it to aternos server, yet i can make a world in aternos with biome bundle and it dosent crash.

thats what i try to do, but it crashed. yet i can do the same on the aternos generate world option, it does not crash.

no, even though i removed every single mod other than otg and biome bundle, uploading from minecraft simply crashes the server.
