Sorry i can not really help. Hopefully there is only a problem with some files between linux filesystem and Nextcloud.
Maybe you can delete (rm) the files manually in terminal e.g. in /var/www/html/nextcloud/data/admin/TEMP (and other directorys) and then run
sudo -u www-data php /var/www/html/nextcloud/occ files:scan --all
If it not works it maybe a bug. Please post more information.
