I doubt you have the same problem as that 2-year old bug report, even though it manifests in the same way.
Can you kindly open a new bug report, follow the bug report template, and perhaps attach a screen recording of what exactly is happening to you. Thanks
I have posted the corrected bug report for this issue here: https:// forum.obsidian.md/t/notes-go-blank-while-editing-except-for-the-note-title-for-no-reason/98230
I have followed this forum’s recommended guidelines, but if you notice I have still done anything incorrectly, please let me know and I will promptly fix it.
