I found these snippets:

https://psalm.dev/r/6e69234550

<?php

$exception = new \Exception();

throw ($exception->getPrevious() ?? $exception);

Psalm output (using commit fe97aa0):

ERROR: UnusedMethodCall - 5:20 - The call to Exception::getPrevious is not used

Since it works with return (https://psalm.dev/r/775f669643) it's likely a variation of the #5540

I found these snippets:

<?php
function f(): Throwable {
$exception = new \Exception();

return ($exception->getPrevious() ?? $exception);
}

Psalm output (using commit fe97aa0):

No issues!
