Based on the screenshot, this isn't a bug. This is more of an error message coming from the game wherein it states that this isn't optimized for the A73 5G.
This usually occurs if the app was downloaded through a 3rd party website other than the official resources like the Google Play store or the Samsung Galaxy Store.
If the game was downloaded through the official sources but is still getting this error message, then it just means the developers have not optimized the game to run on your A73 5G at this point in time and may have to wait until it does support the unit.
Thank you, torishia, for sharing your screen shot of Genshin Impact game, here. It seems that there are compatibility issues with the game and you need to uninstall and re-install it again.
Also, ensure that your device is up-to-date with the latest Software updates.
