Huge obb file for empty project in 4.23 preview

I’ve noticed that after testing 4.23 for my project the packaged (Android-ETC2) files size jumped up dramatically - from 15 mb to 260 mb for .obb file.
To see what’s happening I’ve created a blank project without any starter content and launched a build for ETC as usual - and the size is 241 mb.
What’s going on? Do I have to deactivate something? This size for an empty project is clearly not normal.

Check your active plugins. Disable only those that are necessary.
