So, I ran localhost SQL Server, and I tried to edit the first 200 rows of the table. Then I got this (original in German, I found this through the web):

After that, the SSMS closes. I researched and I found out that this is a known problem if the PATH variable has more than 2 thousand characters. Mine is 1336, so the problem should be somewhere else.
This is the path variable:

C:\Program Files\Microsoft DNX\Dnvm\;
C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;
C:\Program Files\TortoiseSVN\bin
Sometimes, depending on my luck, I don’t even get an error message, but this:

This means that SSMS will restart.
Additional points:
- SQL Server 2014
- The problem exists only on localhost. If I connect to the server, this is normal.
- I have enough RAM.
- Localhost , - .
