I'm facing the same issue—`mpv-2.dll` is missing, replaced by `libmpv-2.dll`. Renaming `mpv-1.dll` from SVP to `libmpv-2.dll` didn’t work.
Until a fix is released, I've set:
[debug]
disableUpdater=true
in the `Plex.ini` file located at `%LOCALAPPDATA%\Plex\plex.ini`.
Additionally, I reinstalled the previous version of Plex—`Plex-1.106.0.276-fe8d1d20-x86_64.exe`—from `%LOCALAPPDATA%\Plex\cache\updates\1.106.0.276-fe8d1d20\packages\Plex-1.106.0.276-fe8d1d20-x86_64.exe`.
Lastly, I replaced `mpv-2.dll` as normal from:
- `C:\Program Files (x86)\SVP 4\mpv64\mpv-1.dll`
to
- `C:\Program Files\Plex\Plex\mpv-2.dll`.
