My drawable xml file is showing unknown character

Question

The last activity that I did was adding a vector (check) and edited the color from black #000000 to white #ffffff. It successfully added. However, my other existing drawable vectors xml file changed into unknown character.

I have tried to rebuild and clean the project, even restart. But none of it helped me. Below are the xml codes of some drawable vectors (I have added a lot of vectors so I'm showing you a few.)

Also, when I run my project, there are no errors in Build.
