error 404, couldnt access preview, tried almost every tutorial, nothing works,

hi my fellow wordpress people i have an issue that started this week, seems like my page has malware and shows a error:404: not found whenever i try to enter, the dashboard and wp-admin works tho, i tried to edit my pages with elementor but it says, couldn′t access preview, i’ve tried permalinks config, re-coding my htacces, using anti-malware software, which by the way detected a lot of threats, i really dont know how to proceed, i dont know where my pages are stored to see if i haven’t lost them, but most importantly how do i get back on the feet the page, i also contacted with godaddy (host) and they told me it was my issue. I have barely modified the website since I migrated and got 2 virus attacks this year, the first one was eassily solved but i don’t know how to proceed in this one, any other help i’ll be glad to hear, by the way i use astra theme.
