Answer 1

Why, 33.8 GB on the HDD does not fit into a 43 GB SSD?

So there is not so much free space on the SSD.
The size of files and the disk space they take up are two different things.
Well, and most importantly - you can not hammer the SSD to zero. It is necessary that it always has 20-40GB of free space.

Answer 2

Lots of moments.
File system layout. Marketing and actual size.
Again, 43 GB ssd is a strange size, "uneven".

Answer 3

In short, hang up, installed the swap file of the system's choice, rebooted the computer.
Added 20 GB of free space
