Confirmed in 26.0.2.
@JervieA20 I mentioned in the original report that this doesn't happen when the world is generated locally
@JervieA20 did you create a realm, or is that a local game?
no i was in operator mode
I've added the crash report as an attachment.
Here’s a video recorded in 26.3 on Windows.
In the video, I created the world with no add-ons or resource packs and spawned the zombie after changing the weather, but the bug still occurred.
