Why are there white squares in unity instead of sprites?

Question

Unity

Hello!
Opened an abandoned project a year after closing and saw that the settings had gone wrong.
Why are white squares on top instead of normal sprites?

Why are the sprites so stretched out?

There are new errors in the console.

I corrected approximately 1 screen, here the text was 3 times larger, there were white squares instead of sprites.

Unity has not been updated. All sprites are in the project, not removed.


If you do not open a project in the unit for a long time, then why do such errors appear?

Answer 1

One of the packages could just be updated (the version is different).
