No clue about rife-app (https://grisk.itch.io/rife-app), I have never used it.
QTGMC works fine in combination with Filtering->Vapoursynth->Frame->Frame Interpolation->RIFE here.
Interlaced source, it deinterlaced to 59.94 and then interpolated to 120ps with RIFE.
=> No clue, what you are on about.

Ps.: on a progressive source QTGMC-deinterlacer isn't applied since applying a deinterlacer on progressive content will damage the content.
