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:
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.
This was actually PXL_20220222_105722730.mp4
