Photoshop saves file bigger after update, can't find a reason.

I use MacBook Pro(16) 2021, Apple M1 Pro, 32GB memory, 1TB SSD.

I used with Monteray, Photoshop released on May 2022 untill yesterday.

But now I updated to Ventura, latest photoshop.

Now I have problems.

Photoshop file saving speed becomes too slow.

And file size is much more bigger now.

I do photo editing works.

Basically begin with CR3(Canon Eos R5) raw image file.

Always make 13 layers.

All conditions are same, nothing changed.

Normally it saved as PSD, size is always on 1.7~1.8GB.

But now it always over 2GB, save as PSB, takes time over 2mins.

It's super annoying and confused.

What should I do?
