[mergeable]

This bug report is missing a link to reproduction at phpstan.org/try.

It will most likely be closed after manual review.

I think a similar thing was fixed recently. Are you using the latest version? If not, try to update and try again.

[michaelvvvvv]

I think it's quite new , installed it in this week.

PHPStan - PHP Static Analysis Tool 1.9.14

[ondrejmirtes]

The PHPStan version is encoded in the stack trace :) The namespace of prefixed dependencies begins with _PHPStan_4dd92cd93 which is the commit :) So phpstan/phpstan-src@4dd92cd93 is 1.9.14 :)

This has already been reported: #8538

The workaround is to install mbstring PHP extension.
