I get this error when trying to run dota 2. I tried verifing game files and also deleting appcache folder. Nothing helped. Does anyone here have experience with this?

32bit Antergos

I pressed zoom option on my panel and immediately gnome crashed and every time I start it it just says something like ‘there has been a crash Log Out’. Tried many things and decided to reinstall system all together. I would like to know for future problems how to solve this.
