Photoshop can't fully export files as jpeg to any mass storage macOS Catalina

so i go into photoshop and load the photo from my hard drive (i have done this on multiple different mass storage devices and) i do my edits and flatten the image and go to export it as a jpg back onto the hard drive the file will begin to save but photoshop will get stuck saving it at some number percent and then stop and ive left it forever and still no more progress so i look at the file on the hard drive and the file looks like it got half loaded and then stopped. half this image is there the rest is just gray and gone i can even open the image in preview and that is how it appears. even with photoshop still trying to save the file i can keep working on the app but cant save to my drive. i have then gone on the computer moved the files to my desktop and onto flash drives and done the same thing in photoshop saving the images in the same place as the original and it works in a snap. i had also just bought a new hard drive to test this and it messed up again. i guess what is the issue does anyone else have this issue or does this maybe have to do with a combination of the computer. i have a 2015 macbook pro and the issues happened as soon as i upgrade to the new macos catalina does this have to do with the os? what do i do please help
