Hello,
Yes the issue is still occuring with the new update.
The only fix I could find is to manually include ac_vendor/php-di/php-di/src/functions.php during the extension loading because it is not done by the ac_vendor/autoload.php.
All the files seems to be there, I reinstalled the extension multiple times, both by composer and by zip install.
It looks like the autoloading is the problem, but I don’t get why
