Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP --
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php
If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
This has been fixed in 8.1

Description:
------------
Catching a TypeError while assigning a wrong type value to a typed property makes that property
'disappear', calling __get() magic method if accessed afterwards, and failing with a
assigning error, even if there is no assigning.
Tested on PHP 7.4.18 and PHP 8.0.6
Test script:
---------------
<?php
class test {
public int $a;
public function __get($p) {
echo "$p doesn't exist?\n";
}
}
$t = new test;
try {
$t->a = "Wrong type";
} catch (TypeError $e) {}
echo $t->a;
Expected result:
----------------
PHP Fatal error: Uncaught Error: Typed property test::$a must not be accessed before initialization
in /tmp/test.php:15
Actual result:
--------------
a doesn't exist?
Fatal error: Uncaught TypeError: Typed property test::$a must be int, null used
in /tmp/test.php:15
("Cannot assign null to property test::$a of type int" in PHP 8)
