Enabling after install fails on Blender 2.93.4

[stibinator]

I'm trying to install Blenderseed blenderseed-2.0.0-beta-0-g6b8f474
In the Blender prefs I install from the downloaded zip, the addon is loaded, but when I go to enable it I get this error:

[appleseed] Python path set to: C:\Users\stib\AppData\Roaming\Blender Foundation\Blender\2.93\scripts\addons\blenderseed\appleseed\lib

During handling of the above exception, another exception occurred:

2.93 is marked as unsupported. I'm not sure what would be required to bring it up to date.
