Hi,
Please try:
1/ Deactivate all plugins and go to Dashboard > Permalink > and click "Save Changes" to update the permalink. After that, try it again. If it work, let's enable each plugin to check what's plugin caused this issue.
2/ If point 1 doesn't work - let's try activate another theme and try it again. If the issues still appears -> seem that's issues from your htacess. You need to re-update that.
Best Regards,
