Garuda Linux is not supported; you cannot generally use packages from my binary Arch Linux repository on other Arch-based systems. It may work by accident, though. If you've built packages on your own then you're on your own anyway when it comes to handling rebuilds that may be necessary after updating packages.

I suspect that in this case the version of ffmpeg that is installed on your system needs to be rebuilt against an updated version of libvpx you have recently installed on your system. However, that has really nothing to do with Syncthing Tray or my Arch Linux packaging.

I'm closing this issue because it is most likely a setup issue on your end and there's really nothing to be improved on my side.

You can still write a comment or re-open the ticket if you have further questions or think it is a problem of Syncthing Tray after all (but please explain why you think so).

I did this in fact I tried rebuilding your synchingtray AUR package and it complained that it was looking for libvpx.so.9 instead of libvpx.so.8

I am using ffmpeg from the arch repos and am fully up to date

trying to reproduce this in arch linux VM just to ensure that its not a garuda issue.

Rebuilding my syncthingtray package won't help because libvpx is not a direct dependency of it. To me this error looks like some other library like ffmpeg or qt5-webengine that use libvpx directly need a rebuild. Since you're saying you're using official packages and you're up to date that is of course rather strange and should not be the case.
