No images showing up in WordPress Dashboard or on website

I updated my PHP version, theme, and plugins, and then noticed that all of a sudden no images are showing up on either my website or in my dashboard (ie. there are placeholder boxes instead of images in the media library and preview images for installed themes). I’ve tried to deactivate all themes and plugins and switch to previous PHP version and back and none of it helped.
If I try to open the link to one of the images on my site, I get this message: Forbidden

You don’t have permission to access /wp-content/uploads/2019/01/237199_Aromatherapy-Rituals-3PC-Hand-Creams-Set-2048×1536.jpg on this server.
Server unable to read htaccess file, denying access to be safe

I also have a notification that “optional imagick module is not installed, or has been disabled”. Not sure if that is related. I tried to follow the steps to enable it, but can’t seem to find it anywhere in my cPanel, so don’t think that option is even available to me.

I’ve read through so many forums already and tried so many things, but none of them seem to describe quite what I have and none of the solutions I’ve tried worked for me.
