Cubase 9 Pro using plugin TDR Kotelnikov hangs CB9

This may be a plugin defect but I just wanted to let you know that if I put the plugin
TDR Kotelnikov http://www.tokyodawn.net/tdr-kotelnikov/
on my stereo bus it works only for the first time I run CB9 after a Win 10 Boot.
If I close the project and CB9 and try to open CB9 a second time, CB hangs during program startup.
I can see an instance of CB9 in the TaskMgr but can’t force it to end. I have to reboot.

If I remove this plugin from the project, there are no problems.

Maybe this should be on the blacklist.

I hoped this helps - John
