Problems downloading from the game?

I wanted to ask if anyone could help me since I have a problem installing Roblox. I have a Huawei y6 (2019) and I can't download it. I had the app once but deleted it because it was buggy. Now I can't reinstall it because this is always shown here (see photo). I also tried all the possible solutions, but it still didn't work.

I would be very happy to have an answer!

I also had this with another app in the Playstore, I just had to wait a day or so and then it worked again, otherwise you can delete the data from Playstore and then try again

Thank you! I will try it!
