I am working on an ionic angular app. When working on it, I was suing ionic cap run iOS -l. when I finished, I ran the app without live this time, but the ion header was going under the status bar even before the screen started, and the same for the ion footer but from the bottom. Moreover, the app is very laggy and not working properly. I have never faced such an issue.

any solution, please

I tried a lot of things such as making a new project and moving just the components, migrating to capacitor 6, and updating the dependencies.
one thing has somehow solved the problem partially, but it should not be done, I imported the core cdn ionic () in the index.html file and the conflict and lag has gone but now spacing and heights are messed up.
