Constant crashes and CPU spikes

I'm having frequent CPU spikes (300% and higher) and crashes in v25.4.1 and have tried every troubleshooting method I know, with no success. Showing high CPU usage (132%) even when idle. Giant spikes are happening with single layer of HD H264 footage with no effects. None of this media or sequences ever gave me issues before and there is nothing new to explain what is triggering this. I've tried dumping cache files and prefs, disabling plug-ins and updating Premiere (I'm avoiding 25.5 at this point for various reasons).

System drive and media drive both have penty of free space and not reporting any issues.

I'm working in a Production project so things are well distributed. I tried starting a new project with minimal media and was still seeing large CPU spikes.

No funky iphone (or other) media and I'm crashing even when playing audio only (mono WAV) or single layer HD H264video. When I switch to another app like chrome, I'll come back to a beachball, but it also happens when I'm not running anything else.

Any help would be greatly appreciated!

Mac Pro 2019

Sequoia 15.7.1

3.2 GHz 16-core Intel Xeon

AMD Radeon Pro Vega II 32GB

224 GB RAM

Media drive - NVME RAID (Sonnet M.2 4x4 Silent PCIe 3.0 x16)

Hi @ds_aliengirl, sorry this has been ongoing. Are you still getting the beachballs when switching between apps or still experiencing the crashes in the Beta, or is it only the error message with CPU spikes, but no crashes? (This is with Beta 25.6 and not 26.0 correct?)

You mentioned you had tried a new project and saw the same issues. Just wanted to clarify if that behavior was reproduced in a standalone Premiere Pro project, or if it is specific to Production projects.

Is the error message you are getting showing up with playback, and is it actually affecting the playback or audio? Do you have a screenshot you can share of this message?

You mentioned you tried rendering to another media drive, but have you tried testing working from a different media drive/location with a few of these files in a new project?

Hey @Dani_V. - I'm still dealing with crazy CPU spikes and would really appreciate some support! I even updated to a 25.6 Beta version to help with overall timneline sluggishness, which sort of helped but now I'm getting timeline errors saying the audio files can't be accessed fast enough due to high CPU usage, which is bizarre because it's not getting hung up on effects and again, I'm using an NVME RAID and have also tried rendering to another internal media drive that is not being used for anything else. But that hasn't helped either.

Hey @Dani_V. -

To answer your questions...

Nothing happening in progress panel.

It doesn't seem related to any specific media as it crashes when I'm in a basic audio stringout (2 or 3 tracks of 48kHz 24 bit WAV files) as well as short sequences of HD H264 MOV or UHD MP4 media. A lot of the time, the crashes occur when Premiere is totally idle.

I am using 3rd party plugins (Maxon and RestorationRx) but disabling the plugins doesn't seem to make a difference.

Hi @ds_aliengirl,

Thank you for reporting a problem and sorry you've been experiencing issues. Do you see any processes happening in the Progress Dashboard up in the top-right corner?

Is this happening with just the specific audio or video file or are you seeing it with different files and formats as well? Where is the source media from?

Any third-party plugins or effects in use?

Sorry for the frustration,
Dani
