Brave Can't Access My Computer; Uploads/Downloads Won't Work

I first noticed this when I tried to download a file attached to an email: “Failed - insufficient permissions.” Shields are down for that site, and I was able to download the file by using a different browser on the same computer.

When I try to attach a file to send via my email, I get this:

“Could not read the contents of folder
Error opening directory ‘/home/acer-desktop/folder’: Permission denied”

I thought it might just be my webmail, so I went to a random website and tried to download an image, and I got this:

“Could not read the contents of Downloads
Error opening directory ‘/home/acer-desktop/Downloads’: Permission denied”

I tried to download the same image on Firefox, and it downloaded successfully.

Brave doesn’t have this problem on my phone, it only does this on my desktop computer. I don’t see any options in “Settings” to allow Brave to access my computer folders and files.

@leslie2,
Thank you for reaching out!
Can you tell me what Operating System you’re using when you encounter this error?

I’m using Ubuntu 18.04.
