NI Battery 4/Eleven Rack Issue

[Stratus]

Starting just about a month ago I began to experience Battery 4 plugin crashes on my system anytime I loaded a net kit or tried to make changes to an existing kit. The plugin would hang with the spinning disk until I eventually closed it which ended up crashing the plugin and generating a mini crash dump. PT then shuts down with an Access error message. Trashed PT prefs, removed and reinstalled Battery 4 and Library with no change in behavior. Upgraded from PT 12.4 to PT 2018.12, removed all other plugins except Battery 4, still no joy. Battery 4 runs fine in standalone throughout all of this.

Shut down my 11R and enabled ASIO4ALL for audio and Battery 4 runs normally except for pops and clicks from switching to ASIO4ALL. Removed and reinstalled 11R driver and it worked OK for a couple kit switches then began to hang again which may suggest a possible memory conflict going on between the plugin and my 11R. Running on Windows 10 Pro, nothing shows up in memory or disk diagnostics. Prior to the start of this all had been normal for about 2 years with no updates to either Battery 4 or the 11R. Anyone else experiencing anything like this?

Thanks.
