I tried changing the resolution and it still is a black screem so... idont know, the werid thing is i played an old version with my laptop and it worked just fine, but now eith a better pc it just dosent want to work, it is a shame since it was a pretty good game and had content that i liked
In recent versions I updated my Unity from 2017 to 2019, and it seems the 2019 version had a problem with the Video player on windows 7, I updated again at version 0.48 to Unity 2020 and it seemed they had fixed it, I tested it on my other pc with a GTX 1050 ti and windows 7, and the animations and the game worked normally.
I'm using windows 10
AMD R5 3600x
And the game work without problems.
Black screen only in animations?
Have you tried running the game in 1920x1080 or 1280x720?
Avast may block some things in the game, try adding the game to the Exceptions list.
If you start a new game without copying the old saves, do you still have black screen?
