i tried downgrading both lua and vlc. that did not fix the problem though

/usr/lib/vlc/plugins/lua/liblua_plugin.so is compiled against lua 5.4 instead of lua 5.2

VLC is not compatible with lua 5.4, at least the dependency "lua" should be changed to "lua52"
There was a change about module : http://lua-users.org/wiki/ModulesTutorial

Attached the PKGBUILD patch to fix the problem (use lua52 instead of lua)
   PKGBUILD.patch (2.1 KiB)

Another solution is to use the following patch that I write (I need to submit it to vlc dev team)
   0001-lua-Make-scripts-compati... (10.8 KiB)

so what is the usual process here? we wait until the maintainer applies the patch? i tried following the wiki to see if i could apply the patch myself, but seems a bit over my pay-grade.

The usual process is to wait for the maintainer to takes a decision on what to do. In the mean time you can build yourself VLC with the patched PKGBUILD.
You just have to download the PKGBUILD with the associated file (for example using yay -G vlc), then apply the PKGBUILD patch (manually or using the patch command), and finally build the package like any AUR package using "makepkg -si"

I reported the problem here: https://trac.videolan.org/vlc/ticket/25036

thanks benjarobin. that worked. makepkg -si initially threw a pgp key error. i just re-ran makepkg with the --skippgpcheck option. probably not the right way to do it, but i couldn't figure out how to fix the key issue.

Looks to be fixed with VLC 3.0.11.1-2
