wp.blockEditor.RichText multiline prop deprecated?

Built a multi component block using examples from your github as a guide. Getting an error saying:
wp.blockEditor.RichText multiline prop is deprecated since version 6.1 and will be removed in version 6.3. Please use nested blocks (InnerBlocks) instead. See: https://developer.ww.wp.xz.cn/block-editor/how-to-guides/block-tutorial/nested-blocks-inner-blocks/

I have read your documentation and I have scoured the internet for months, even tried to pay people to help me implement a solution that will a) be compliant with your new format, and b) migrate my existing block elements to a new format so users with the plugin installed don’t have to rebuild all the blocks they’ve created using the plugin. I have yet to find a solution to this issue or someone who can help me solve it. I am at the end of my rope here. Please. Help me. I’m begging you. I know I’m not the only one experiencing this issue.
