Can you attach the world where you can recreate this? Seed + coordinates of where the portal should be placed would be better

Thank you for your report!
However, this issue is Invalid.

Your game, launcher or server is modified.

Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.

Given MC-121098 causing suffocation in this case (which, granted, I haven't tested in a while), my guess is that this is specifically a mod-related issue. If you can reproduce it on a vanilla setup, please comment.
