After Effects fails to launch, crashes on startup after mediacore

Yeah, that's fine. I would also try to clear your preferences on one of the machines. Press Ctrl + Alt + Shift (Windows) or Command + Option + Shift (Mac OS) while launching After Effects. You can release the keys when you see the Startup Repair Options dialogue box.

As for uninstalling, either method should work, but also make sure to read the Cleaner article thoroughly for those steps.

I can't open AfterFX to get to the help menu to enable logging. I can't open any Adobe video app on any machine. There is one log in C:\Users\[username]\AppData\Roaming\Adobe\After Effects\25.4\logs from the last attempt which looks relevant.

• Upload and share a link to the "After Effects Log.txt" file in the "logs" folder

I don't see how to upload here, do you mean upload to the cloud somewhere and put the link in a reply?

Sorry our messges crossed. I will do nothing more unless you approve! I have checked the email of this account and that's the one I'm signing the crash reports with. I'll send a log manually as you requested, from both machines, before attempting uninstall. If I uninstall, do it from windows or from CC app?

I can't load AfterFX, PPro or Media Encoder on either machine. Cannot even load app to make a project, crashes on splash screen.

Sorry to hammer this thread! I thought to generate you a crash report, but After Effects loaded successfully! I created a project and it worked OK. I tried to load PPro as well but it crashed, I sent you a report. I closed and tried to reopen AfterFX but it crashed as well, sending you a report. 

So it does load occasionally, maybe 1 out of 20 times? I can see GPUsniffer loading each time. I just tried loading AfterFX 10 times with no successes. I don't know if you caught that my win 10 box has the same issue, never used a eGPU there in the past. 

Win 10 Pro, 10.0.19045

ASUS motherboard i7-11700K 128GB RAM

RTX something, I think 2070

After Effects 25.4

Well that's no good. I'm still not seeing a crash log show up in our system with your email address. To be clear, are you trying to work in the same project and it's crashing on both machines? Or just opening AE on both machines is crashing?

If it's a specific project, what happens if you create a blank one and import your project into the new one?

As for completely uninstalling, here's the support article on how to use the Creative Cloud Cleaner tool.

Before doing that, though, generating logs might be more helpful since we're not getting the crash report. 

• Open the Help menu

• Select "Enable Logging" and close AE when prompted.

• Relaunch AE and reproduce the crash.

• Go to "C:\Users\[username]\AppData\Roaming\Adobe\After Effects\25.4\logs"

• Upload and share a link to the "After Effects Log.txt" file in the "logs" folder

To keep the logs as clean as possible, make sure you don't do anything except reproduce the issue.

Thanks,

I went to my windows 10 box so I could keep working, updated after effects, and it now does the same thing. I sent a crash report with this email addy. It also crashed PPro like the other win 11 machine. So I'm frozen until resolved. Maybe Windows update? But the win10 box is still on KB5062554. These two computers that are crashing adobe at launch are pretty unrelated, other than being attached to my license, and having the most recent adobe updates.

There have never been network drives mapped, though occasional file sharing on LAN.

Thanks to all for your help. I went through the permissions tree and all seemed normal. I had not renamed GPUsniffer. David suggested uninstalling Neat but that had no effect on the issue. He also commented on previous conditions coming back, and I used to use an eGPU. Someone commented somewhere that they had a similar situation and used DDU to clean out old drivers, so I tried this but it did not seem to help or harm in my case.

If it's time to do a clean install of all Adobe apps and creative cloud app, what is the procedure? Uninstall in CC first, or through windows? Should I use Creative Cloud Cleaner tool? Or if you have any other ideas, please let me know! Thanks again for yout help!

I would also suggest (temporarily) uninstalling Neat Video.

The Last logged message seems to indicate somehting is going awry with our applications connection to your GPU, which is something Neat might possibly be interfering with now (even if it hadn't in the past).

Thank you for your help! I did send in the crashes using crash reporter, I think three of them using this address in the last couple days. But I can easily generate more! I could paste a log in here if it's not getting through. At first AfterFX was only generating DMP files and no logs, which seems like maybe it couldn't write to that folder? Whereas PPro wrote logs from the beginning. 

Should I be setting permissions for Media Encoder too? Is this all so mongled that I need to completely remove all traces of Adobe and start over?

Anyway I will follow those steps and reply back soon, thanks again
