When I go to the "set default app by file type" option, all typical PS file associations list Adobe Photoshop CC 2019 as the default app, except for .psd file type. There is no default app set, and no matter how many times I try and set PS as the default app, it still shows as "choose default app".
Furthermore, underneath the .psd file type it says "Adobe After Effects Photoshop" (screenshot attached).
Of all the file types I would expect to work without fail, it is a .psd!
