Playback Broken After Playing Footage From Source Window

Hey guys, 

*Edit: Bug report is at the bottom of the post.

This issue is driving me insane and I hope someone can clear things up.

Every time I load a clip into the source window, playback freezes.

The only way to fix it is to save and restart the program. I have to do this for EVERY SINGLE CLIP.

If I import a folder with multiple clips and create sequence from clip, there's no issue. As long as I don't have to touch the project or source window, that is. Which we all know is impossible.

However, if for any reason I need to find some B-roll somewhere, playback breaks. I cannot figure out what's causing this.

At first I thought it had something to do with a large project, corrupted project, HEVC footage, sequence mismatches, etc. but that's not the case. Video or audio, it does not matter.

It's been happening since V23 and I can't go back to V22 because that version caused me to lose multiple edits every day. The famous autosave bug.

I've been running Nvidia studio driver 517.40 for a while now. That fixed other issues, but this one remains.

I recorded the issue; you can find the wetransfer link below in case the attachment does not work.

It's a video of a completely fresh project, with a random clip I downloaded for demonstration purposes.

WD Ultrastar 16TB (Archive drive)

Corsair RM750X 2018

Premiere Beta 23.1

Premiere 22 had too many other issues, which was the reason I moved on to 23.

Premiere 23 (Full release) also had too many issues, which is the reason I moved on to Beta 23.1.

Premiere Beta 23.2 would not even load. So that's not an option either.

- Already updated graphics driver (Tried 517.40 and above - have not tried the new 527 yet).

- Removed graphics driver with DDU and reinstalled from Nvidia website.

- Already tried 100% fresh Premiere install with reset preferences.

- Already had my RAM replaced earlier this year, didn't fix the problem.

- Yes, my RAM is on the motherboard QVL.

- Computer is running at stock settings, no overclocks whatsoever.

- Thought it might be a faulty GPU (VRAM) but doesn't seem to be the case since it only happens in Premiere.

- What I haven't tried is a complete Windows refresh, but I'm currently not in a position where I can take the time to go through a full rebuild of my system.

- BIOS is not on the latest version, but I doubt that would solve the issue. Other programs are fine.

• Issue - Playback breaks after activating source window and playing the footage. If I import a folder with multiple clips and create sequence from clip, there's no issue.*Edit: Playback breaks after opening the export window, then returning to the timeline. Exporting via media encoder with Premiere open also breaks the playback.
