I finished this game completely without mistake, including the "finish" page 2 month ago but no single achievement has been achieved.

To solve the problem, I looked through the Steam Community's guide page.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=229968551

At the bottom of the link, the writer said he resolved the bug by restarting Steam and loading the slot.

But It doesn't work for me.

So I tried googling but this link was the only answer I could get.

https://steamhost.cn/steamcommunity_com/app/265890/discussions/0/540734168235673570/

In that link, the developer said he will look into it but it still happening.

Anyway It did not resolve the issue by restarting steam client or reload finished slot or verifying integrity of game files.

For now, I have no idea what I could to do to solve the problem.

If you have an idea that might help, please let me know. Thanks.

P.S. I do not speak English well. If there is anything you do not understand, give me a chance to explain it again :P
