S_Transition - Filmroll crash

Hi, after applying S_Transition, then changing the default transition in s_transition to Filmroll,
it crashes when played back in the host, other options from the default transition drop down work ok, & Filmroll transition works ok when applied on it’s own ? :man_shrugging:

I use S_FilmRoll in S_Transition but it just freeze 1min in host, will not crash.
