Bug report

Code snippet that reproduces the problem

https://phpstan.org/r/2bff6a23-9c9a-492f-a6d6-e34319e0e054

enum Enum1: string {};
enum Enum2: string {};

/** @var value-of<Enum1|Enum2> $bar */
$bar;

causes a fatal failure (probable infinite recursion)
Internal error: Internal error.

value-of of a union of enums seems to be the cause.
This may also be similar to #8835.

Expected output

No issues

Totally! I just stumbled on this due to a composer update, so I checked and this a regression introduced in 1.10.0
