Hi thanks for a great plugin. I've reinstalled the docker but getting this error:
an error occured, that has not been caught:
Array
(
[type] => 8192
[message] => Return type of M4bTool\Audio\Tag::offsetUnset($offset) should either be compatible with ArrayAccess::offsetUnset(mixed $offset): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice
[file] => phar:///usr/local/bin/m4b-tool/src/library/M4bTool/Audio/Tag.php
[line] => 158
)
