Can't login to Sendy

Hello,

I couldn't log in to my Sendy v5.2.6 installation. Then I upgraded to v6.0.2 and the problem is still there. It redirects back to the login page.

I tried changing the password. I tried clearing the cache and tried different browsers. I tried to re-upload all Sendy files via FTP. I tried disabling 2factor auth in DB.

My PHP version is 7.4. Perhaps Sendy is looking for the session file from folder ea-php73 but it doesn't exist on the server. The server is based on WHM/cPanel v104. This is the error log:
