Quicktime YUV 10bit Uncompressed exports corrupt video

PAL Quicktime YUV 10bit Uncompressed exports have corrupt video

Source video: PAL 720x576 4x3 Uncompressed YUV 10 bit Quicktime, uncompressed PCM Audio
Export format: Match Source (Uncompressed YUV 10 bit, Quicktime)
Adobe Premiere/ME 24.6.1
OS Sonoma 14.6.1
M2 Mac mini Pro 12 Core 32GB RAM
Internal HD for Premiere/ Stornext SAN fibre storage for media
AJA IO X3 Thunderbolt 3 for monitoring (v17.1)

Steps:
1. Load a PAL Uncompressed YUV 10 bit Quicktime into Premiere 24.6.1 project
2. Set in/out points
3. Right click on source clip and Export Media
4. Choose Format: Quicktime, Choose Video Codec: Uncompressed YUV 10 bit 4:2:2, Match Source
5. Export

Expected results: Trimmed QuickTime files to same spec as source that import and play video and audio fine in Premiere and Quicktime.
Actual result: All exports complete successfully but resulting files open with green scrambled video in Premiere and black video in QuickTime Player.

Exports attempted from master clip in project and from sequence made from clip, also tried exporting via ME.
Have tried turning hardware acceleration off in prefs as well.
Exporting the same clips in Premiere/ME 23.5 works correctly.
I HAVE to export to Uncompressed 10bit mov Prores etc not an option.

Thanks,

Adam.
