Need Help: Opening a Premiere Pro 2026 Project in Premiere Pro 2023 – Downgrade Doesn't Work

Hey everyone,

I'm trying to open a Premiere Pro 2026 project in Premiere Pro 2023, but I'm completely stuck.

The thing is, this project is extremely simple. It only contains:

• A few video clips
• Some basic cuts
• One audio track

There are no advanced Premiere Pro 2026 features being used—no AI tools, no Generative Extend, no Auto Translate, no new effects, no Motion Graphics, no third-party plugins, nothing. It's literally just a basic edit.

Here's what I've tried:

• ✅ Used the Premiere Pro Downgrader website.
• ✅ It successfully created a downgraded .prproj file.
• ❌ But when I open that file in Premiere Pro 2023, I get this error:

• Is the project actually damaged?
• Is the downgrader not converting something correctly?
• Has anyone else had this issue even with a very simple project?

I don't understand why it won't open because there aren't any features that Premiere Pro 2023 shouldn't be able to handle.

Has anyone successfully downgraded a 2026 project to 2023?

If you've found a solution, please let me know. I'm really hoping I don't have to recreate the entire edit from scratch.

Thanks in advance, guys! 🙏
