Unexpected Error on export?

Hi guys,
I’m getting a little desperate here.
I made a post the other day about the issue I’m having when exporting my stems in Cubase 12
(Send FX Issue when exporting stems in Cubase 12?):

But unfortunately, didn’t get any responses to it.
I updated my Cubase to the latest version hoping it would fix that bug but it’s now gotten worse, I cannot export anything at all getting this error when I try:

Can anyone help or can guide me as to who I can get in touch with?
Please help :frowning:
