How can i open it?

Hi @Nut_Nut7222

Sorry for the delayed response. I completely understand how frustrating it can be. I agree with the solutions Monika shared, and I hope they helped resolve the issue.

If you're still facing trouble, please feel free to send me the file via DM. I can check with the Product team to see if there's a way to recover it. Let’s try our best to get this sorted for you!

Looking forward to your response.

You could try and download a higher or lower version (whatever applicable)

Or share the file with Adobe as stated in the warning.
