Wow! Thank you for all your help!
ANEWCIYNE, I will recommend it based on the advice you gave me in the video comments.
As for the issue of starting the new one, I changed the name of the folder with the files and now it starts.
Specifically, it seems that the "é" in "Résop Paz Yandere True" was the reason why it did not start. (Probably because "é" is not a character usually handled on Japanese PCs.)
After playing ANEWCIYNE, I also played the new one!
However, I have a cold and cough, which makes it difficult for me to play, so I will report my play after I get well.
