@Timo-JM As requested please upload your veg to a file sharing site such as Google Drive then share the link so others can download it and examine it. Don't worry that your source material won't be available. It's the settings and FX that need investigating.
zip is not on my list of the formats. Beside that, I am not sure what are the upload rights of every group here. So, maybe he has to uplaoad that on an external webspace really, and post here the link.
@Timo-JM, I confirmed it in the first post I made. It works fine in VEGAS Pro 20. That's why I want to see your VEG file (not the media, just the VEG file).
It's not possible to put it here.
I agree, it is not possible to load it directly to this forum. You have to upload it somewhere and give us a link to it. Google Drive, Drop Box, your own website, anywhere you can upload the file and then share the link with us.
