WebM Renders with Alpha channel from AME end up corrupted.

[RokasBal]

I'm attempting to export WebM files trough Adobe Media Encoder, however every file with "Include Alpha Channel" enabled I try to export ends up corrupted and looking the same, no matter the settings used for it. I tried multiple different settings, however every time it ends up with the same result.

I'm attaching 2 exported files, both are the same composition, but used different export settings, yet ended up corrupted in the same way.

I tried removing and reinstalling the plugin, however that didn't seem to fix the issue either.

Disabling alpha channel fixed the issue, however it's required for me.

Everything sucks about this plug. I think this poster is dead but I managed to make a workaround by outputting my stuff to transparent AVI (uh oh) before running it through FFMPEG with ffmpeg -i "avi" -r 30 -t 2.99 -an -c:v libvpx-vp9 -pix_fmt yuva420p -s 512x512 -b:v 400K output.webm for my case with Telegram stickers to success.
