I've attempted 3 renders, and although it worked last time I tried all 3 failed at various points in the rendering process. There are only a few differences between these attempts and the last working one.
Those two being that these are taken from a server rather than a singleplayer world and I have recently upgraded my video card.

We really need the full log to be able to see which versions of Fabric and mods you're using. You can remove the chat, but nothing else, please

You're also using an old version of the ReplayMod. Try updating first.

I didn't remove anything other than chat, that's all that was there, I'll try updating

Can you provide the debug.log, or, if that doesn't exist, the latest.log (taken directly after the bug occurred). These logs are located in .minecraft/logs.

That should be the one from the roughly 60% then failure attempt, with chat cleared

Yeah sorry about that, I appeared to have replaymod-1.15.2-2.3.0-b1
