Premiere export stuck at 48% Can I cancel the export and keep the progress?

[luke unsworth]

I'm trying to export a dance show of around 1hr 40mins (4k) but the export is 'stuck' at 48% (although task manager shows viable activity on the GPU e.g regularly peaks like its processing frames). I was trying to use PP's 'smart rendering' however the render files seem to dissappear randonly so I'm now trying to render the whole thing. Can I stop the export now? Or will progress be lost?

I should mention that although some H265 files from a Canon R5 & Nikon Z6 (via Ninja V) were crashing Premiere I have since transcoded them to Prores 422 and the system seems happy with the footage.

Do you know how to fix it?

If you stop the export, then your export progress will be lost. Period.
