reverting fabric api to 0.45.0 fixes the issue

fabrics api changelog -

Bump versions. (modmuss50)

• Preventing END special events with dimensional api (#1938) (kohanis)
• Registry sync packet compression II (#1853) (deirn)
• Fix attribute modifiers inject limiting other mixins. (#1928) (Jared)
• Use the correct information when throwing Exceptions for failed tests. (#1927) (Jared)

guessing somethign got changed with how immersive portals handels the dimensional api ?

use fabric 0.12.12. on 1.18.1

edit: same crash with 0.45.0 api now. :(

this is used in a modpack im developing, and may take time to figure out the interacting mod causing this.. if it is caused by another mod.

edit: updated all my mods..not fabric api.. .. works fine.... updated fabric api... fails to create a world.

reverting back the fabric api update... also keeps the same crash happening. cant update fabric api or crash will continue to happen even if down graded the api mod.

edit: if i dont update the fabric api... everything works as intended. .... update it.. breaks world load.. reverting the update, also breaks world load.

Can confirm the same issue. Have been unable to get everything except a local server instance running with 0.45.1 and immp.

Should be fixed in 1.1.8
