VLC Super Resolution black screen

Hello everyone,
I'm posting on this forum because I couldn't find a solution after several hours of research on Google and also on this forum.
I have a RTX 4060 and I'm using the version 3.0.21 of VLC and the latest version of Nvidia driver (572.42). I wanted to use the Super Resolution upscaling, so I activated it in Nvidia control panel and also in VLC under Direct3D 11 parameter. Unfortunately, after activating it in VLC, I've a black screen and I can only hear the sound of the video and see the subtitles. I tried to disable the Hardware Acceleration Settings but when I do that, the subtitles aren't showing anymore.
Do you guys have any fix for this issue ?
Thanks in advance,
Chakrastyl

Please post the whole full messages log. Open Tools -> Messages (set Verbosity to 2)
before you start the playback, keep the messages
window open during the whole process and then paste the
full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.
Also upload a
short sample of your
original problematic file to WeTransfer.com or Disroot.org and then post the link to the file here.

Sorry for the low quality video, I couldn't find a way to improve the quality using Windows game bar.
Thanks in advance for your help,

You're right, it's working when I'm playing H264 videos but not H265 ones ! Thank you for your message, I'll do that.

Sorry for the double post, but I tried to create an account on
http://code.videolan.org but it's not working since yesterday, it says that "Your account is pending approval from your GitLab administrator and hence blocked. Please contact your GitLab administrator if you think this is an error.". But I authorized it and I can see the authorisation on my GitLab account, so I'm stuck.
