Galaxy S8 Plus Secure Folder Does Not Open.

[wakilnikzad]

When I try to open Secure Folder, instead of login page it just shows me a blank screen. I searched for a solution on the internet and tried many things including: Restarting the phone, Reset Settings, Reset Network Settings, Force Stopping the Secure Folder App... but none of them worked. Someone told me to Uninstall the Secure Folder App either from Google Play or Galaxy Apps, but I couldn't find the uninstall option there.

I had moved too many important images of mine in the Secure Folder when it was working. Therefore, I don't want to lose them. I didn't try "Factory Data Reset".

Any help would be appreciated.
