Reproduce:
Load MP4

Scenario1:
 - VS/Deint/qtgmc
 - Preset Custom with EdiExt MFDIN(old)
 - Queue and Start: CRASH [attachment=3683]

Scenario2:
 - VS/Deint/qtgmc
 - Preset Custom with EdiExt MFDIN(old)-TRT
 - Queue and Start: CRASH [attachment=3684]

additional phenomenon: vspipe keeps vram full and keeping gpu load high despite queue having crashed

Does the Vapoursynth Preview work?
I guess you are running out of vram.
With 16GB vram on hd content I get:
Code:
Requested amount of GPU memory (1592786944 bytes) could not be allocated. There may not be enough free memory for allocation to succeed. UNSUPPORTED_STATE: Skipping tactic 49 due to insufficient memory on requested size of 1592786944 detected for tactic 0x1b099f7ac29a2a6a.

no, preview doesn't work either.

(it's a bit strange since i used it successfully in the past.)
Are you sure you used it on HD content? (works fine on SD content here)
hm iirc i used it on 576p and 720p, not above
in your sample you used it on 1440x1080, so that is probably the problem.
I suspect that it will still work fine for you on SD content.
