Exported videos do not play

[Superlevure]

Hi everyone

I hope someone here can help. 

I have been using PP for more than a year now and suddenly my exported videos do not play. 

I don't do anything other than 'match source setting' and changing the resolution or aspect ratio. 

I have no idea what is going on. I have tried different settings and I have reintalled PP. Nothing seems to help. 

Here is one of my attempts: https://1drv.ms/v/s!ArHPynK2HR4Sm9s-1nmR21iuNksg0w?e=TaZAnq

My first question is why are you exporting a video with a frame rate of 119.880?

What is your source video?

The source is from a Sony camera. I have tried to export at 30 and 60 fps, with no changes.

Delete the Media Cache and Media Cache files:

If that doesn't work, try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.
from here:

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver)

If that doesn't work, try creating a new project and import the old one into it.

Amazing - my problem is solved! 

I did not even have to go beyond the first step; I did a "Delete all media cache files from the system" and it solved it. 

I'm surprised to see how the cache can affect new projects. 

Thank you very much @Peru Bob and @gerikp for your help.
