aerender.exe stuck at launching

Please check if multiple instances of aerender.exe or After Effects are running in the background. Sometimes, previous processes don’t close properly, causing conflicts. Open Task Manager and end any aerender.exe or After Effects processes that are still active. Another thing to try is running aerender with the -reuse flag, which prevents it from launching a new instance of After Effects if one is already open.

Another possibility is that After Effects is waiting for a response from a modal dialog, which can block aerender.exe from proceeding. Open After Effects manually to see if any error messages or pop-ups appear that need attention. Additionally, you can also disable GPU acceleration in After Effects.

Hello @GERGELY221500940vli,

Welcome to the forum. I am Kevin from Adobe Support, a moderator here. While we await an expert response from the team or the community, I hope you have tried troubleshooting steps like deleting cache and resetting preferences. Even restarting the machine can help. If you are clear of these steps, and you still cannot render, then that is a problem. It appears to be system specific since it works on other machines. It may be your enterprise environment in the way of your workflow. I am not sure everything will work as expected if there is a hardware issue or software conflict. I also suspect that the Xeon chips may be at fault since they are not called out in system requirements. I'll try to find out about that.

I hope the community can assist you shortly. Let us know how it goes.

Thanks,
Kevin
