Game not work after build apk and run in Android

Hello, I have a problem, I am developing a game for Android, I was testing and working perfectly until Wednesday. Today when I went to compile a version to try to test it on the Android phone (Xiaomi) the game compiled but there was a sequence of about 20 warning with this message:
“Compressed texture (punchIcon) is used as icon.This might compromise visual quality of the image. Uncompressed format might be considered as better import option”

Only the game icon appears normal.
Here is a screenshot of the problem, which is occurring to me after installing my game apk:
First Image is the bug not work, second image is runing work game, and third image is a icon work good.

If you Google for this exact error, you should find your answer.

I already tried to google it, but all solutions are for problems with icons, and my problem is not with icon, but with the game that does not render the images after generating the APK and installing on Android phone.

For those who are or have the same problem as the one I reported, I managed to solve it as follows:
Step 1: Create a new project;
Step 2: Export the package, right-click the Assets folder and then ‘Export Package’;
Step 3: Build and run the project

This solved the problem I had and compiled the game correctly.
