I agree. 1.1.383 is very buggy and unstable on two of my systems. One is an iMac running Sierra and the other is a 13in MBP running High Sierra with R 3.4.2 on each. Same (un)reliability issues on both: random crashes when switching from console to terminal, when switching file directories, when importing or exporting datasets.
Following @mara I decided to try the new daily build before dropping back to the previous version of RStudio. When I open the daily build, it crashes immediately with the following error output:

I know dailies aren't ready for daily use yet, but I thought this might help still.
