'Premiere Pro renders to m4v and mp4' problem

[baloghn]

Dear community!

After a little halt (about 2 months) without video editing, I got back to Premiere Pro 2018 CC. I remember everything worked fine, but now when I want to render out the edited clips in h.264 it creates a ~0kb M4V file and an MP4 file which is only audio. I have not changed any settings before.

I looked for solutions and already tried these:

- Check the "Export Video" and "export audio" boxes

- Check the multiplexer settings (it says "MP4" and "Standard")

- Tried Adobe Media Encoder too, but that has the same problem

- Tried to export the video without checking the "Export Audio" box, and that created a useless M4V file and an XMP file

- Tried to set from CUDA rendering to OpenCL and Software, nothing worked.

Another strange thing is that a small dot appeared after some words in the program inside. I attach a photo to see what I mean. It's like it's showing that there are problems with the settings, or I don't know...

Please help me because I'm already really upset that I'm always spending my life more with problem-solving rather than producing...

Thank you very much in advance!

(Here is the picture of the dots, they appear elsewhere, too)

If it happens in all/new projects as well i would have started here to reset the Preferences: How to reset (trash) preferences in Premiere Pro?

Thank you, tried about 3 times, but didn't work.

So it happens in all projects and in brand new projects as well?

Yes, I tried with a new project, imported only 1 mp4 file, but when I tried to render that, the same result happened.

Then i would have used the Creative Cloud Cleaner Tool to uninstall Premiere Pro and then re-install Premiere Pro.

In the meantime I have solved the problem: 
download the latest updates of your drivers from your computer manufacturers page ( I have a Lenovo so I went to Lenovo's webpage and it automatically found the updates.) 
So the solution is UPDATES. Nvidia, Intel, whatever you have, search for the latest updates.
It will solve the encoding problems.
