"Unknown file type" Error

[Lancepro]

Apologies if this has already been discussed but I could not find the thread.

I have an unusual error when using PPSSPP (Gold/Regular) on android.

I can load up games that are in my recent list just fine but when I load a game from the directory (even the ones from the recent list), the emulator gives me an error:

"msf:662
Could not load game. Unknown file type: content://com.android.providers.downloads.documents/document/msf%3A662"

Please the note the same game can run if I click it from my recent list. Also the set of error numbers changes every now and then.

- I have checked to make sure the file is an .ISO.
- I tried running a .7z file as well.
- I re-downloaded and unzipped a new ISO.
- I restarted my phone.
- I reinstalled PPSSPP both Gold and Regular.

I uploaded a screenshot of the error.

Hope you can help me figure this out. Thank you.
