any ideas?

check if the extension mbstring is installed on you server.
You haven’t mentioned what is your stack so I can’t help anymore.
In ubuntu you will something like

sudo apt-get install php7.2-mbstring

Thank you that was it. I ran

apt install php8.0-mbstring and email working.

You’ll need more modules. I just installed a SuiteCRM 8.4.1 server with PHP 8.2 and used this

sudo apt install php8.2-common php8.2-mysql php8.2-xml php8.2-xmlrpc php8.2-curl php8.2-gd php8.2-imagick php8.2-cli php8.2-dev php8.2-imap php8.2-mbstring php8.2-opcache php8.2-soap php8.2-zip php8.2-ldap php8.2-intl -y

You’ll have to adapt that to PHP 8.0, but as you can see, it’s better not to stumble on the problems of each missing add-on, one by one…
