Error in the jounalization logs

Hello to all,

since a few days I have errors in the jounalisation of Nextcloud last stable version.

Error scss_cacher OCP\FilesNotPermittedException:

/var/www/html/lib/private/Files/SimpleFS/SimpleFile.php - line 149:

require_once("/var/www/html/console.php")

looking at the information I see that it can't delete the files 
in /var/www/nextcloud/data/appdata_oc3tes1q2v8u/css/core. 
Files like bd5d-7764-css-variables.css.deps and bd5d-7764-css-variables.css.deps.zip. 
So I renamed them to .old. so it created other files like bd5d-aa14-css-variables.css 
but it still spits on the old files.
Errors can be generated easily by doing:
sudo -u www-data php occ maintenance:repair.
Could you give me a way to solve it?
