Adobe Premiere Pro 26.5.2 Severe Freezing Issues on MacBook Pro M4 Pro (24GB RAM)

私も全く同じ症状でした。（Macbook ProのM4Pro、OS26.7.1、PremierePro26.5.2）
結果的にナレーションの音声データの形式がm4aで、HE-AACという圧縮方式だったことが原因だったようです。
AuditionでWAVに書き出して差し替えたところ、PremiereProの挙動がもとに戻りました。
もし、音声ファイルにm4aを使っていたら、差し替えてみると解決するかもしれません。

I am at my wits end working with Premiere Version 26.5.2!!  So close to jumping to Da Vinci!!!

Hello ​@rozigoGG 

Welcome to the Premiere Forums! Freezing issues can be very difficult to diagnose, so we may need a lot of specific information from you as we investigate. Some of the context below can be helpful.

• Does it affect all projects or only some?
• Does it affect new, empty projects?
• When did the problem first begin? Was it when you upgraded to Golden Gate or where you on Golden Gate running 26.3.2 fine and then upgrading to 26.5.2 introduced the freeze?
• Have you tried launching Premiere holding the Shift key and Clearing your Caches?
• Is the freeze immediately upon launch or does it appear after editing for a while?
• What Panels do you have open when you notice this behavior? (a screenshot of this could be helpful)

When Premiere is freezing, it could be helpful for us to have something called a Sample file. It will tell us what background processes Premiere is running that could be contributing to the freezing behavior. If you could follow the instructions below when you run into this issue, we would appreciate it.

MAC sample file:

1. Open Activity Monitor and identify the Premiere process (you can use search to filter for only Premiere)
2. In Premiere, get it into the hanging/unresponsive state
3. Switch back to Activity Monitor and right click on Premiere then choose > Create Sample
4. Click Save, then save it as a text file somewhere.
5. Then, you can DM me and either provide us the link/access to this file or I can send you a link to upload that file, whatever's easiest.

I will supply a private upload link for any material via DM on this community site. Let me know if you receive it.

Hoping to help,

Amy
