Default D50 Crashes With Roland Cloud - Can Anyone Reproduce

Looking for help reproducing this if anyone happens to have a Roland Cloud account. I'm getting constant crashes with the Roland D50 plugin on load. Usually after some spiking of the channel volume. Other Cloud plugins are working fine. This is 100% reproducible here.

Specs: Windows 10x64
Reaper 6.02 x64
D-50 Versions: VST2, VST3 (both 64-bit) - v1.09 (latest versions according to the Cloud Manager)

Steps to Reproduce:

1. load a blank project
2. Load the D50 plugin (VST2 or VST3)

Result: spike in audio and crash

Windows Event Viewer shows this:

Fault bucket 1583285995529746607, type 4

I went looking for the .dmp files in that folder and they don't exist. I also see some entries relating to Bonjour and Eucon but I removed the Eucon plugin and closed the Eucon applications and still got the crashes.

Oddly, after a few weeks, I just got it working by:

1. Loaded up the VST2 (loud pop - meters spiking, Reaper output muted)
2. Ran the All Notes Off action
3. Ran the Reset MIDI Devices action

By this point, the D-50 became disabled in the FX MCP's effect bin. Then I...

4. Clicked and dragged the D-50 VST3 from the FX Browser and dropped it directly over the D-50 VST2 in the effects bin
5. Then I enabled the D-50 VST3

Now it works for some reason. Saved this as a Template and it works.

No idea what's going on with the D-50 and my system, but in case anyone else has this issue, give this a go. I've at least got the VST3 version working here.

Note: I think the crashes/issues I was experiencing may relate to the Bonjour service used by iTunes, EuCon, and iLok. Whenever Reaper would crash with the D-50 plugin, there'd be additional logs referencing Bounjour and EuCon.
