I’m working on a MacBook M2Pro 16 memory, I updated Premier 2024 to the latest version and all the memory started disappearing. Tell me what to do, I can’t work

This is definitely a thing, and I don’t remember running into it before. The screen shot below is for a relatively simple project, tutorial videos. So the 1080p sequences are almost completely cuts-only edits on a single video track with no effects, and the media format is 100% screen captures created using native macOS screen recording. Each sequence is about half an hour long, in Premiere Pro 24.2.0. (It was also happening before the last update.)
With that memory usage in mind, note that my Mac (M1 Pro MacBook Pro, macOS 13.6.4) has 32GB of unified memory, and rarely complains about memory usage in Adobe photo and video apps. It is alarming to see these Adobe applications requesting many times more memory than is physically installed in the Mac. But I don’t necessarily panic about that, because I understand that the reason macOS doesn’t reach that error state until memory usage is well beyond 100GB is because of the way macOS can use RAM compression and swap files to juggle the balls in the air as long as it can. The concern is that these apps managed to push macOS over the cliff, which I rarely see. This Mac is usually rock solid for weeks with Adobe apps.
There are only two features that are frequently used in these sequences. One is Essential Sound; I have applied Dialogue adjustments to all audio (it’s narration). I am using transcription to do text-based editing (very useful!); at one point I wondered if Premiere Pro was having trouble managing that new feature’s metadata or something because it was hard to think of other features in use that could cause such a problem.
Originally I had all sequences in one project, but because macOS was telling me that opening it made Premiere Pro want over 100GB of memory, exceeding even the ability of macOS to manage it, I broke it up so that each lesson uses one project with one sequence in it, and am now managing the job as a Production. But all that does is keep each individual project from overrunning macOS memory management, because each sequence can still use many tens of GB when opened.
At one point I tried exporting a project to XML and opening that back in Premiere Pro, in case there was corruption, but that didn’t help; the new version exhibited similar memory usage.
The Adobe Media Encoder memory usage is so high because I watched it add roughly 10GB of memory use for every 3 to 5 minute in-out segment of a sequence that I add. Now I stop adding to the queue when AME exceeds 100GB memory usage, render those, quit AME, and then restart it just so I can add more sequences to render.
Also — Premiere Pro and AME are not releasing memory when projects/sequences are closed or deleted. If AME racks up over 100GB memory usage and is finished rendering, the only way to free up that memory is to quit AME…because deleting all already rendered sequences from the queue doesn’t reduce memory usage at all.
I don’t know if this will help, but I have seen similar memory complaints in threads about other Adobe applications, for example in the Lightroom Classic community: Lightroom Classic memory usage spirals out of control, into the hundreds of GB, until macOS throws its hands up and cannot go on. I only mention this in case the Premiere Pro engineers need to confer with the Lightroom Classic engineers, like if it’s actually a bug in OS memory management. That link is just one example, there are numerous similar Lightroom Classic customer threads that you can easily find with a web search.
The unpredictability is also similar, in that for both Premiere Pro and Lightroom Classic, it isn’t happening to everyone. It isn’t even consistent for me. Although I have obviously seen this problem in Premiere Pro, I spend even more time in Lightroom Classic and have never seen it misbehave with memory like some are describing.
