Possible resolution:

I haven't had the time too look into this in details but since this happens in a Rollback, the solution may be similar to doctrine/migrations#1143

Thank you for the help, and please let me know how I can help further.

Actually using TransactionHelper in Doctrine\ORM\EntityManager fixes the issue:

line 237:

    public function transactional($func)
    {
        if (! is_callable($func)) {
            throw new InvalidArgumentException('Expected argument of type "callable", got "' . gettype($func) . '"');
        }

        $this->conn->beginTransaction();

        try {
            $return = call_user_func($func, $this);

            $this->flush();
//            $this->conn->commit();
            TransactionHelper::commitIfInTransaction($this->conn);

            return $return ?: true;
        } catch (Throwable $e) {
            $this->close();
//            $this->conn->rollBack();
            TransactionHelper::rollbackIfInTransaction($this->conn);

            throw $e;
        }
    }

Do you know if any DDL statements are executed before the attempt to commit? The issues you are linking to should only arise when combining PHP 8 + PDO + MySQL or Oracle + DDL statements.

Maybe that's because of the "purging database" step? Does it maybe work with DROP + CREATE TABLE?

[PapyDanone]

@greg0ire thanks for putting me on the right track. One of the fixture files contained an ALTER TABLE statement which caused the issue.
