Dreamweaver CC 2017 - 2017.5 build 9878 - node.exe killing my system

Using windows 8. Ever since I downloaded 2017.5 I have one major and one minor issue that ultimately make DW unusable.

1) Starting dreamweaver creates a node.exe process which *kills* my high-end system for several minutes. I can't do anything on the system for several minutes after opening dreamweaver

2) Alt-tabbing into dreamweaver now has a few seconds of delay every time. So if you work flow is "Edit, save, alt-tab, refresh, alt-tab back to DW" You end up waiting several seconds waiting for DW each time you alt-tab into it. This seems related to the git integration - I use git on every project I work on, but I wish I could disable that integration if it means DW is going to studder and pause for between 300 and 2000ms every time I alt tab into it.

The work around I've found is to close DW, kill all node.exe proceses, and rename "C:\Program Files\Adobe\Adobe Dreamweaver CC 2017\node" to "C:\Program Files\Adobe\Adobe Dreamweaver CC 2017\node_disabled".

I've done some basic process analysis of what node.exe is trying to do and it doesn't appear to be obvious. I see lots of reads into DW's files and lots of registry key reads - nothing seems specific to my set of working files.

I'm not sure what all I'll lose by renaming that node folder, but waiting several minutes for DW to load while my system is unusable is pretty much a deal-killer for me and I'll be moving on if I can't find a solution.

Anyone have any fixes for this issue?  I've noticed other people have posted similar issues on youtube (Dreamweaver CC 2017 process "node" high CPU usage from startup - YouTube ) and other things in forums about this. How we can disable whatever features is causing the node process to runaway?

Thirdly, this is more of a rant, when are they going to restore "wrapping" functionality for snippets and hot-keys for snippets.  Removing those features impacted me quite a bit.
