What should I check when a Descript export is stuck rendering at the same percentage?

If it’s been parked at the same number for a while, I’d first check Descript’s status page, then refresh or reopen the project and try the export again. If you’re publishing a web link, a local export can be a useful workaround during a publishing/render incident; if the local export is the one hanging, try a smaller resolution or a simpler test export to narrow it down. Descript also notes that web-link exports have an 8,192-pixel scene-size limit, so oversized scenes need to be resized. If it keeps failing at the same spot after that, send Descript support the project link and the export type/percentage rather than repeatedly retrying the exact same render.
