While editing (in Premiere Pro 2020.  14.9) Adobe pushed the Premiere Pro 2021 (15.0) update on me, and my PC totally crashed.

When I rebooted, Premiere Pro 15.0 was installed (14.9 gone) and I tried to open my previous project. The PP program opens, but when loading the project data, the whole computer totally freezes and only a hardware shut-down will recover it. WTF???!!!

Same story when trying to open ANY previous project.

I unistalled all Premier Pro 15.0 software and reinstalled Premiere Pro 2020 (14.9). But, *******, same thing. So now I have effectively lost ALL my previous project work?  

What is the solution please Adobe??
