CRITICAL BUG Unable to play NS2 as of build 248

Any time I start ns2 since build 248 I get a crash before menu screen, saying a fatal error has occured

THINGS I HAVE TRIED
-Computer restart
-Cache Verify
-Reinstalling NS2+deleting all mods/appdata related
-Reinstalling graphics drivers with a clean install
-Rolling back graphics drivers to a few versions back

Sent logs and minidumps via reporting system, if it means anything my log.txt stops after saying my render device.
