[BUG] LOGO Invalid, not appearing

[ropdwr]

33333.png works fine here. (properly fading in over the first 25 frames and fading out over the last 25frames)
22222.png fails with:

Avisynth preview error: -> Import: unable to locate "����" (try specifying a path), error=0x2

only real difference I see is that the bit depth of 22222.png is reported as 32bit and the bit depth of 33333.png is reported as 24bit.
Opening the file in an image editor, saving it with a bit depth of 24bit instead of 32bit and the new file works with the filter.
-> seems like the filter does not support 32bit pngs

Cu Selur

Here are all 24bit.
But can't display LOGO,
But the 2017 version can display LOGO
