3. Have you made any changes to your device that might affect verifying SSL certificates, like modifying the OS Certificate Authorities?

no

4. Can you verify that the date is set correctly on your device?

yes, please find attachment_ time.png

I receive the same SSL Certificate Authority error when testing in an emulator running Android 9. I suppose that isn't completely surprising, as Android 9 is no longer supported by Google, which means that it no longer receives updates to the list of Certificate Authorities.

There are a few things I can note about this.

1. Privacy Browser currently does not support downloading a file over a connection that produces an SSL error. There is an existing feature request to add that behavior, which I intend to eventually implement, but probably not anytime in the immediate future.

Feature #708: Allow Save URL to connect to invalid SSL certificates

2. You might be able to work around this problem by importing the Certificate Authority into Android's CA store. A while back I wrote some instructions for doing this for the ISRG Root X1 CA, which you can probably adapt to your needs. Note that you need to import the GlobalSign GCC R6 AlphaSSL CA 2023, not the certificate issued by that CA to the website.

3. If you are greatly concerned about your online privacy (I understand that not everyone is or needs to be, and that many people use Privacy Browser for reasons other than privacy), you should upgrade to a newer version of Android that receives security support. There is only so much that Privacy Browser can do to protect your privacy on an unpatched OS.

I should probably also note that you might be able to work around this problem by the Download Provider to be an external app in Privacy Browser's Settings. Then see if you can find an app that supports bypassing SSL certificate errors.
