Hi and welcome to the forum 
This is a know issue, there is a item on the backlog of the team that develops nautilus. Add your findings to the issue on gnome gitlab so the developers know that there are more people who experience this issue.
As a workaround I would set your systemd logsize to something sensible so it does not use all the space:
$ sudo nano /etc/systemd/journald.conf
Example for 50MB
SystemMaxUse=50M
more workarounds are here
