How to fix problems with old apps on new android?

Question

Android

Need to run an app that crashes on android 11 but works on 4.4.
It opens on top of another application, I think this is the problem. When the host application is not installed, it starts without problems, but if you install it, it crashes and cannot be opened.
If you really need a name, write. Thank you!
