I can't open a old Premiere Pro file and it crash when I try to update it

Hello,

In last october, I worked on a PP project. Today, I tried to open it but the version was obsolete - ok, no reason to freak out, I will convert it in the new 24.1 version.

However, when I converted my project to the new version, an error suddenly appeared. Then, it tells me that I need to update my Premiere Pro but it is already updated in the current version... I reset all my settings and restarted my computer but nothing changed.

Can someone please help me?

Thanks.
