One line summary of your issue
Battletech crashes immediately after pressing play button in steam

What platform are you running the game on?

What operating system do you use?
Ubuntu 21.04

Which version of the game are you running?
1.70 Buisd ID 4719583

What DLC do you have installed?
Urban Warfare

Please explain your issue is in as much detail as possible.
Pressing the play button in Steam results in no video or audio and almost no disk or cpu usage. The button changes to stop for a few seconds and then reverts to play. As far as I can tell, no logs are produced, so I am including the output from running it in a terminal. I have tried uninstalling and reinstalling the game. I have removed all save files, and all DLC with no results. I also tried running the 1.81 beta in case that had any effect. It did not. Not really sure where to go from here.

Have you tried verifying your files?
Yes

There is definitely no log there, are you saying? If so that means the game never even got started, as that is almost the first thing it does.

I can't say that crash log says a lot to me, I don't see any of the usual suspect like missing or old libs or video drivers.

Of course this game ceased development well before Ubuntu 21 came out!

Has this game ever run on this machine? What video card and driver are in use?

There is no log created.

It has run on this machine before. I don't remember the last time I played it. It was likely back in Ubuntu 20.04 or 20.10 though.

My graphics card is an nVidia GeForce GTX 1660 Ti and I am using the nVidia 460 driver, though when this started, I was running the 450.

I guess we have to assume this is a problem with this game under Ubuntu 21 then.

This is asking a lot of you, but can you run this by any Ubuntu support resources you know of, forums say? I'm hoping the Linux experts there might see something in that log that's beyond me.

The log shows a SIGABRT possibly related to Mono. There are a lot of similar reports online, often but not purely related to Ubuntu, and also often related to Unity engine games. I found one where something related to alsa was triggering a crash in Mono during a Unity game. You may want to try downgrading or upgrading Mono, depending on what options are available to you.

However, I am on Arch Linux and for a while now I have generally experienced incredible instabilities in Unity based games that often result in total system crashes. I have many other games using different engines that push my setup harder and for longer, with no issues, but Unity games just implode and take my whole system down. I have noticed this since Vulkan became more common and I suspect there is something going on with the combination of Unity, Vulkan and other libraries and drivers they use that is resulting in this. Valheim uses Unity and Vulkan on Linux too and did the same to me, with regular and complete system crashes, but if I force that to run under OpenGL, my issues vanish and no further crashes.
