Scratch disk, import errors, can't create proxies
I'm hoping to find out what is keeping me from editing editing 4k footage located on my SanDisk Extreme Portable SSD 1TB.

When I try to create a new project and save the working file on the external I get a scrach disk error.

When I continue with the scratch disk set to my documents folder and import my footage I get an import error.

After I click OK the footage is in the project and I can still drag it to the timeline.
When I left click the footage to create proxies through media encoder it fails.

I have tried changing the scratch disk locations, clearing my caches, uninstalling premiere pro and media encoder and re-installing them. No success.
I then started a new premiere pro project on my desktop, as well as putting a clip on my desktop to import and create a proxie with and it worked. I'm hoping it's an issue with settings or something because I have edited a lot of projects from my external without any problems like this. I need to edit from the external because the amount of footage is too great to keep on my computer.
Here's my computer specs

Any help is appreciated,
