HOW TO FIX "UNABLE TO RENDER ERROR" 0x80131501 IN VEGAS PRO 21

Vegas video montage software is widely known as pretty glitchy application especially if we are speaking about latest versions.
Newest Vegas 21 Pro is no exception. I run into problems almost instantly.
Right after i’ve decided to render video clip.
Upon export attempt application showed me error:

0x80131501 

How typical!
To fix things up i just took DLL library [RenderAsDialog.dll, which is responsible for export dialog] from previous
Vegas Pro 18 [sub-version 284 to be precise] and substituted original file with above mentioned.

RenderAsDialog.dll can be downloaded [here].
File is packed with [7zip].

You can rename original file into something like RenderAsDialog.dll_ before copying over.
Just to be safe if something goes wrong.

Original file location is here:

C:\Program Files\VEGAS\Vegas Pro 21\RenderAsDialog.dll 

On positive side Vegas 21 STILL works in Windows 7 without any problems.
