Welcome to the forum! 
Please see:
If you chose proprietary drivers when booting the live ISO, you already have the NVIDIA proprietary drivers installed.
Do not install them from the NVIDIA website. Remove them the same way you installed them.
See Configure NVIDIA (non-free) settings and load them on Startup - Manjaro
Note that I’ve removed your screenshots of terminal output from your first post. Please copy and paste terminal output using preformatted text instead of uploading screenshots of text.
Each image uploaded to the server makes forum database backups larger. Search engines cannot read screenshots and one cannot copy and paste from them without an OCR program.
Please edit your post accordingly.
