You need to read the service requirements to ensure CodeIgniter runs correctly:
CodeIgniter Requirements.

Try modifying ;extension=mbstring in the php.ini file to enable extension mbstring.

Switch to Laragon, then all you need to do is just copy the php version into its php folder
and setup the php.ini file.

You also need to install the vc17 redist file.

The new version of Laragon has become a paid version, and it doesn’t seem like the right choice for me.
