When exiting a world while riding a happy ghast high up, the next time I enter that world, I leave the happy ghast and die from falling

Dear Sir/Madam,

I am writing to tell you about my experience with your new update and problem with that.

I'm playing on the PE version (version v1.21.113), and the official version of Minecraft is downloaded, the latest version. I've been playing Minecraft since 2020. The problem is that when I exit a world by pressing "Save and Exit" while riding a happy ghast high up, the next time I enter that world, I somehow leave the happy ghast saddle and die, falling from the height. I'm assuming this is a code or technical, or syntax error, but unfortunately, I've lost two hardcore worlds this way. I'd like you to resolve this issue. I’m really with this new update but it brings pain.

I look forward to hearing from you soon.
