Vital plug-in not found (VST2) on M1 Mac despite opening with Rosetta

I’m trying to open an existing project on my new M1 Mac in Ableton Live 11, but I get a Vital VST2 “plug-in could not be found” error. I have checked off “Open with Rosetta” in Ableton and tried rescanning, restarting, etc. multiple times without seeing any improvements. Any help would be much appreciated!
