The Inside Donald Trump DLC caused issues for the game on Linux based machines. Because of this we had to remove the Donald Trump DLC from the Anniversary Edition of the game as it was causing it not to launch at all. We would eventually like to re-enable this, however, we are limited by resources at the moment.
What we'd recommend trying is uninstalling the game to start with, then install the base version of the game and see if it runs for you.
After that add back on the Anniversary Edition content and it should be on the new fixed version for Linux.
It's also worth noting on Linux-based machines even without the Inside Donald Trump DLC there can be a long delay between launching the game and it being playable. It appears to be freezing but if you leave it around a minute it should boot.
We apologise for any inconvenience caused.
