So I the CURL thing solved the V16 studio issue, still have issues with no thumbnails displaying or unable to edit anything on 17beta.
For anyone, who like me, couldn't downgrade CURL as my cache was empty, download the older version here https://archive.archlinux.org/packages/c/curl/ and then save it in the /var/cache/pacman/pkg/ folder then use the command Polarity put below.

IMPORTANT!
Since version 19.1.3-2 this package will not download automatically the source file from the upstream site.
To build this package you will need to manually download the file from https://www.blackmagicdesign.com/support/family/davinci-resolve-and-fusion and place it in the same directory with the PKGBUILD.
This would reduce the mess in this package, making it more readable and clear. Also bypassing the required information from the upstream URL is not allowed in an automated way.
