Is this a regression ?
How many apps did you test besides the mentioned ones ?
While wine (at least winex11.drv) doesn't handle desktop switches correctly (it minimizes then restores instead of unmapping/remapping), this usually doesn't result in the app terminating.
Those are the only apps I use with Wine. I didn't test any other. At first I thought there had something to do with The Sims 4 and StarCraft 2 originally running in fullscreen but Sonic After the Sequel doesn't so it can't be that either. Also believed it could have been how those apps handle being out of focus but this only happens if they are in a different virtual desktop. If they are just below another window, they don't close, from what I could see.
