TVAI 5.1.1 Stable - AION model "error": conversion don't start!

Update on the situation:

I believe that nothing has been done by the developers to at least “try” to solve these alleged video memory “problems” for the AI model “AION”… despite as I said I have a HIGH end computer (Ryzen 7 7800X3D + 32GB DDR5 6000Mhz dual channel + RTX 4070 Ti SUPER with 16GB of GDDR6X video memory), I keep having serious problems with this AI model: let’s say that with 1080p videos the result is fluctuating (I have to admit that it “seems” that with the new versions the problem has subsided, often I was able to convert 1080p videos in slow motion at 6x, but not always). … but today I tried with an AVC video in 4K at 30fps and, with the latest stable version 5.0.2, the encoding process froze just before it started, it gave me error immediately!

As always I attach the LOG file created by the program!

I hope, dear developers, that you can solve it soon, because so many like me are in this situation, and it starts to be really frustrating!
