Reaper 6.08_ Win10 Pro Latest _ Cannot Remove VSL Synchron Player Track !!

[sostenuto]

Reaper plays all other Tracks properly, and any can be 'Removed' except VSL_Synchron Player. This has been on many earlier Reaper projects (small) and never this issue.
Fresh load, with only this VST3i and still will not 'Remove'. Long times to load it, and seemly never finishes removal. Track plays various selected presets normally.
Same problem if trying to Close Project, with VSL Synchron Player loaded.

All else perfectly normal. Any suggestions ??

Downloaded /Installed ALL VSL Downloader & Synchron Updates !

Seemed to have solved, but next Project, with (3) VSL Synchron Player Tracks, repeated earlier problem. Was able to 'Remove' one Track, but Reaper locked again when trying to "Remove' another. Will contact VSL next week, as this seems most likely source.
