Error when trying to open my scenes?

Back in December, Blender 3.0 released and I announced that I would be switching to it. As a drawback of this choice, scenes that I made using the new version cause an interface error in older version (Blender 2.9 and older) of the program.

Lately I have been getting more and more questions about why this is and how to fix it.

I've addressed that this would be an issue but forgot to say how to deal with it here. My apologies for that, I've answered on Instagram because that's where I got most of my questions but forgot to share elsewhere.

My solution:
1. Open Blender.
2. Manually open the blend file with the scene you are trying to use.
3. Select everything in the scene (may need to re-enable the selector tool for this. Tutorial is already up on how to find this under the Blender Tips post)
4. Copy and paste everything into a brand new file in your preferred version of Blender.

If you already use Blender 3.0 and newer, this is not an issue and you should be able to open the file normally.
