the file exists but does not seem to have any video -

[Sfang]

If i try install potplayer it works but whenever i try open video files it gives the error message "the file exists but does not seem to have any video"
see picture:

Note, it all worked good until i installed the DaVinci Resolve 17 software for video editing...

Anyone that know what the issue is?
Note: I can play up the video files via other media player such as Windows 10 built in photos & movies + media player

win10 64x
i9 9900 CPU 3.6ghz
gtx 1070

Did you install OpenCodec with PotPlayer... Maybe your DirectShow video codecs got messed up, try re-registering them with: https://www.videohelp.com/software/Codec-Tweak-Tool
MS players use Media Foundation filters/codecs. Also, try installing LAV Filters.

But shouldn't the coders be okay if other media players can play up the files without problem?

I checked the tool and it shows this:

So now directshow for 64x which is my setup?

I also made a log of all my codecs:

Windows 10 media players use Media Foundation, third party players like Potplayer, use DirectShow (VLC and MPV use FFMPEG). Some audio/video programs can sometimes mess with system codecs/registry settings.

So what should I do now?

The sherlock utlity that i found on a other site states the following:

Use this to see if any codecs are disabled: https://www.nirsoft.net/utils/installed_codec.html it also lets you enable them... Reinstall your video card drivers. If nothing works, you might need to de a system restore.

Thanks for the help.

After some changes within the system i managed to get it done, this time also with installing without the "additional codecs" within the installer.
