[HELP] rife - encoding freezes

Using 4k input, and this script:

# Imports
import vapoursynth as vs
# getting Vapoursynth core
import sys
import os
core = vs.core
# Import scripts folder
scriptPath = 'F:/Hybrid/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))
# loading plugins

# adjusting output color from: RGBS to YUV420P10 for NVEncModel
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, matrix_s="2020ncl", range_s="limited", dither_type="error_diffusion")
# set output frame rate to 60fps (progressive)

clip.set_output()

encoding stalls a bit, but then starts, and constantly works, no pauses.
Using a Geforce RX 4800 (with 560.81 Studio drivers): VRAM usage ~10,8GB (video decode is running at ~70.90% and 3D usage is at ~90-95%)

Since I can't see the settings and you didn't post them:
What does the Vapoursynth script look like?
(side note: not enabling 'Scene change' is usually a mistake, unless your whole clip is just once scene)
What GPU are you using?
How is the CPU and GPU (VRAM/3D/Decode) usage?
What drivers are you using?
Is a virus scanner running in the background? (aside from Windows defender?)
Any hardware tuning tools running in the background?
How are the CPU and GPU temperatures?
(for me GPU is ~45-55°C and CPU is clocked at 5.27GHz and at ~70-72°C)
What is your RAM usage? (mine is 18-18.7GB running the above script and NVEncC as encoder)

=> not having any issues here
Wild guess is that something is interfering or bottlenecking the decoding.

Looking over at https://github.com/styler00dollar/Vapour...cnn-Vulkan I see no changes in the past 6 months that should influence the speed.
This does not look like an issue with the rife filter itself, but either your system or your other settings.

Ps.: rife-app (https://grisk.itch.io/rife-app) is something different from Hybrid.
