Does Wine show a crash dialog? If so, save the backtrace from there and attach it to the bug.
What version of Wine were you using when Skyrim last worked? And, of course, try to perform the regression test that Rosanne suggested.
No crash dialog or backtrace. The only sign it's crashed, other than the game window disappearing, is the wine output "err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0xa15ba20f".
Are there any WINEDEBUG options that would reveal more information on the crash?
The last version it worked on was 2.16, so the regression is very recent.
