I found these snippets:
https://psalm.dev/r/9889237f4f
<?php
/** @return ($n is int) ? int : float */
function double(int|float $n): int|float {
return $n * 2;
}Psalm encountered an internal error:
/vendor/vimeo/psalm/src/Psalm/Internal/Type/TypeParser.php: Unrecognised parse tree type Psalm\Internal\Type\ParseTree\TemplateIsTree
from psalm.

While this is a bug, the issue is that the annotation isn't correct according to https://psalm.dev/docs/annotating_code/type_syntax/conditional_types/
With correct annotation https://psalm.dev/r/c8d874453b there's no crash
(there's another bug though as the error makes no sense)
