Your project could be hacked. My recommendation: first read this article:

FAQ My site was hacked

After that I would recommend checking whether you still have a clean backup. If necessary, ask the support of your hoster. If so, delete all files and the database and restore the backup. Then change all access data in the hosting. This should solve the problem.

Finally, you should secure your project. This is described in more detail in the article here: https://www.ads-software.com/documentation/article/hardening-wordpress/

If you need personal help at any point, try contacting your hoster’s support first. Alternatively, you may also find someone here: https://jobs.wordpress.net/
