I found this in shadow wiki:

TGen was moved to its own repo on April 3, 2019 as of this commit for organizational reasons

Does the error has something to do with this? And how can I get libshadow-plugin-tgen.so?

[Rob Jansen]

You should first install TGen as described here:
https://github.com/shadow/shadow/wiki/1.1-Shadow#tgen-setup

That will install the tgen binary into ~/.shadow/bin/tgen

The shadow.config.xml file in the minimal example is still referencing the old location of /home/vera/.shadow/lib/libshadow-plugin-tgen.so. You can edit shadow.config.xml so that the tgen plugin line reads like this:

<plugin id="tgen" path="~/.shadow/bin/tgen" />

[Rob Jansen]

I just pushed a fix to the resource/shadowtor-minimal-config example with the path change I mentioned above. Please pull and the new minimal config should work (assuming you have already installed tgen).

Thanks for reporting!
