I can't render wav file from imported midi

[Kuri]

Hello! ^^ So, I tried to make my own Ust by importing midi into Utau... But when I inserted text and tried to render it to waw (to have backup file) it showed me error window ,,Can't render it to waw" (I have it written in japanese so I don't know what exactly it says but it's something like this). I tried to render parts or single notes, checked tempo, tried different midi to test if there wasn't any problem with that exact midi, but nothing worked. Usts works. But not midi and I don't know what's wrong TwT.
I'll be happy for any advice.

Did you download the MIDI from some other source? If so, please share the link.
Did you create the MIDI yourself? If so, what software did you use?
