Shipping plugin crashes after Mollie update

Hi,

I updated Mollie this morning, and since then my shipping plugin Bpost prevents me to see my orders.

This is the line that keeps repeating in the log journal from the shipping plugin (mollie logs are clear from errors) :
2020-06-03T06:45:01+00:00 CRITICAL Declaration of WC_BPost_Shipping_Logger_Handler::handle(array $record) must be compatible with Monolog\Handler\HandlerInterface::handle(array $record): bool dans /srv/data/web/vhosts/*(my website url)*/htdocs/wp-content/plugins/bpost-shipping/classes/class-wc-bpost-shipping-logger-handler.php à la ligne 7

The error comes from the other plugin, but since it’s related to your update, I post here in the hopes you could understand where it is coming from, and maybe help me find a solution.

It has been months both plugins interact weirdly with each other (confirmed by Bpost), impacting directly on the order payments. I hope a fix is coming soon, the situation is worrying.

Thank you for your time, have a nice day ??
