Poor Performance on Illustrator 29.6.1

Earlier this week, I opened an AI file with no performance issues before Illustrator 29.6.1. However, it's now unusable from a performance standpoint; it frequently locks up as I pan around the file, zoom in and out, and attempt to interact with anchor points or perform any action.

Here are my specs: MacBook Pro (16-inch, 2021), M1 Max, 64 GB RAM, running Sequoia 15.6

File Characteristics:

• 235 artboards (all but two artboards are 32x32 px large)
• 13 layers
• 2.4 MB
• 12636 paths
• 61417 points
• The assets are all vector-based, and no effects are applied
• No linked files
• A single font family and six weights are used for text in the document
• In general, this file is pretty simple. It's a suite of icons, with different style and color variations on different layers, which we hide/un-hide when needed. I never had any problems with it the last time I opened it.

I've been trying to troubleshoot this myself, and here's what I've done so far:

• It is not related to running external displays. The problem persists whether they are connected or not.
• It is not a network issue. The problem persists when the file is located locally on my desktop or is hosted on a remote server.
• I've uninstalled and reinstalled Illustrator. The issue persists.
• The number of artboards doesn't seem to affect performance. The original file has 235 artboards (though they are small—99% are 32x32 pixels). Removing all but 10 artboards does not improve performance.
• I updated MacOS to the most recent version from the previous one, and the issue was the same before and after the update.
• It doesn't appear to be specific to that file. I created a new file and set up the same layer structure (albeit without any actual shapes or other elements), and the poor performance persists. I also checked previous versions of the file, and those are now performing poorly as well.
• Other team members have experienced the same issues, so it isn't limited to my machine.
• I've been reviewing the activity monitor, and I'm not seeing any unusual performance indicators. Even Illustrator doesn't appear to be taxing the CPU (~87% of my CPU is idle while running it) or using an unusual amount of RAM (> 3 GB).
• I utilize a few plugins, such as the Astute Graphics suite. Other users who don't use any plugins are experiencing the same issues, so it doesn't appear to be related to plugin usage.

My best guess, based on what I've tried, is that it seems tied to the number of layers. When I create a new file, it performs fine. The performance takes a nosedive as soon as I add the number of layers I have (which is not excessive, mind you). I hadn't opened this file since I updated it to 29.6.1 a few weeks back, nor did I open a file with more than 3-4 layers, so I suspect that the update introduced some bug tied to the layers, causing the performance drop.

Has anyone else experienced this problem?
