[How to get City of Heroes running on Linux]

I've tried this on a 2011 era Macbook running Ubuntu 20.04, and it crashes the OS.  In summary:

 

- every step seems to work up to and including the start-up of Tequila.

- Tequila gives the error message about the missing .exe for Paragon Chat.

- so I double-click on Homecoming 64-Bit.

- the "LOADING" legend appears in the center of the screen.

- the OS crashes and reboots.

- if I try again, the tequila.exe file has vanished, and lutris gives an error message that it can't find it.

- if I copy it back over from my Downloads folder, and run lutris again, it crashes again.

 

When lutris starts, I get these messages in the terminal window:

Anyone have any insight?
