Invalid String Position Error when encoding to Prores AW LT with Resolve

I have Resolve 18.6.2 and decided to test the latest Voukoder Pro update again. (Have been using normal Voukoder for my tasks before because it was stable).

I'm getting "Invalid String Position" Error when encoding to Prores AW LT with Resolve. I'm exporting individual clips. One sequence rendered without an error. On the other one the error raised for the 5th clip. I removed clips 1-4 and tried again. The error popped out again and again for this clip on different render percentage. I tried to figure out what's the difference between those clips but have not found any fx or noticeble differences. The camera and codec were the same for all clips. Tried other exports for other source codecs and the same error randomly raised again prety often after some exporting effort.

Rendered the same sequence using prores_ks scene with no issues.
I also tried to find a log. Could you specify a log path please?

The reason I'm trying the Prores AW is it is almost 2 times faster to render with and LT mode has much better PSNR then Prores KS LT (with my reference video):
Original Prores LT: 49.05

Prores AW LT: 48.42

Prores KS LT: 46.99

here are the logs

Converted with such command:
