I have a question, so I would like to play Genshin Impact on Playstation but download it to my laptop, can I then transfer the saved state?
Unfortunately, PS4 does not support crossplay, unlike the other platforms
No, unfortunately the PS4 version does not support cross-save.
afaik this is unfortunately a limitation on the part of Sony and not miHoYo's fault - that is to say, this will probably not change in the near future.
No, and you can read that everywhere on the Internet. It was known from the start that Sony did not support this.
The PS4 version uses the PSN ID and not a miHoYo account and as the latter are hacked, it's a good thing that Sony doesn't participate.
