2017.2.5 Mac freezes while working after a few seconds

When I start working after a few seconds when I modified a file my mac freezes.

If I only start the ide nothing happens.

To solve the problem my self I tried the following (without success):

Downgraded to 2017.2.4

Invalidaded Caches and restartetd

Tried to copy the files I tried to change to make sure that they are accessible.

Log-File shows the following error:
