Slow Premiere pro

Hi, my premiere pro 25.4.1 has suddenly become extremly slow. Kind of unworkable. Maybe a coincidence but it started when I upgraded my MacOs to Sequoia 15.6.1

I work with a big project, just over 200 MB. I've tried to start a new project and import the main sequence of our film, and the project then landed on 20 MB, but with no result. Of course I´ve tried cleaning cache, working on low resolution and with proxies.

Just about to finish this project but this makes it very difficult.

Any help or tips in sight?

Best

What are the complete computer specs, including hard drives (how many, what kind, what is on each, what capacity, and how full)?

Hi, and thanks for your reply.

The project is a documentary, 3 years + in the making. The last year the projectfile has not grown much. Premiere has worked fine until about two weeks ago. I've had the same computer and the same external harddrive altrough the project

Specs are:

Apple M1 Max

APFS 1TB Harddrive 550GB left

12 core

RAM: 32 GB

Videomaterial is on a 8 TB Seagate Onetouch. 800GB left. Its a slow external harddrive, but it has worked until now.

Thankful for any possible solutions.

Is the Seagate Onetouch an SSD or HDD?
