Visual Studio crashes when trying to open an existing project

So, when I'm about to open a solution, the VS just crashes.

I don't really know what I should attach here, so there is a little piece of the error code after force quit... if it's needed, I can insert there the whole, but it's quite long.

A piece of the error code:

Here are some more lines, that should be something to work with as this is the crashed thread's error. pthread_kill, abort, cache_getImp?

Allright, so seems like 8.8.1 update solved the issue, so far at least.
