Getting low level C++ stdlib runtime errors like "std::exception" (and I'll expect the other is std::vector) means something is badly messed up. And the best way to badly mess up low level stuff in Pro Tools is... plugin issues. Which could also explain why this is seen in all rooms if you've installed the same plugins on systems in those rooms. So that is where I'd start troubleshooting.

So try basic standard troubleshooting: Try just trashing prefs, that not fix issues then move all .aaxplugin files out of the plugin folder, trash prefs and test with only the standard Pro Tools plugins installed which will automatically be put back when you start Pro Tools.
