SFZ Player not loading samples as VST in Ableton Live 10

I noticed that Squinky’s excellent SFZ Player is paused at “Progress: 0” when loading a .sfz file when running Rack 2.2.0 as a VST or AU inside Ableton Live 10 on macOS.

I wonder if Live is restricting the files from being loaded for some reason, since it works fine in Rack standalone and as a VST in Bitwig. The total size or location of the sample files in the soundfont doesn’t seem to make a difference.

Just posting in case anyone else has noticed this, or managed to fix it.

Update: It works in Live 11, so I should probably just stop delaying and upgrade.
