Please set this as critical, I can't work with my Access aplication at all in 2016.
Crashes with last stable as well.

The issue in the log file is an out of memory exception. This is an unfortunate problem we keep having, since we're memory-limited by the VBE context and keeping the parsing tree of code and all inspection results in memory is ... difficult.

There is an open issue around RAM consumption where some tips can be found at #3347.

With Rubberduck3 this should be greatly alleviated because we push the state management into a separate process, which allows us to be free from the VBE memory limit :)
