Throwing exception in a child results in empty ParralelError in catch()

[FluffyDiscord]

I am confused

$pool->add(function () use ($selectedCompressor, $sourcePath, $targetPath) {
                try {
                    return $selectedCompressor->compress($sourcePath, $targetPath);
                } catch (\Throwable $throwable) {
                    throw new CompressionFailedException($sourcePath, previous: $throwable);
                }
            })->then(function (?CompressionResult $compressionResult) use ($stats, $updateUi, $sourcePath, $targetPath, $fileEntry) {
                // not relevant
            })->catch(function (CompressionFailedException $exception) use ($stats) {
                // works
            })
            ->catch(function (\Throwable $exception) use ($stats) {
                //  also throws, but its empty Spatie\Async\Output\ParallelError - no message, no code, weird trace, what is going on
                \Symfony\Component\VarDumper\VarDumper::dump(['anything' => $exception]);
            });

// the compressor compress function

public function compress(string $source, string $target): CompressionResult
{
        throw new CompressionFailedException('test.zip');
}

Either the exception type filtering doesn't work properly, or I am missing something.
