About the name of the file in the error, this is a problem of Android (or the 3rd party plugin we use to select the file). Instead of receiving the "normal" path to the file, Android is using a special path like this:

content://com.android.providers.media.documents/document/video%3A8006

And this path doesn't use the original name of the file. So we cannot know the original name, only the one that Android provides us (in the example above, "video:8006"). Unfortunately I'm not sure if we'll be able to fix this, you can open an issue if you wish to look at this later.

Example:

This was actually PXL_20220222_105722730.mp4
