Hi, I have a similar problem.
Occurs with version 1.92 only.
Reproducible with "Reaper" and "Cakewalk".
If I uninstall version 1.92 and then install version 1.91, everything works fine.
Does other version work for you?
I reported the problem to support on May 24th, 2020, unfortunately no solution yet.
