Fatal error in version 6.3.3

My client’s website didn’t show any product images on bundle blocks because the block had changed a bit with the latest releases. After doing debugging with other plugins, I noticed that the issue was the outdated block of your plugin on the pages where the images didn’t show (images were visible on the product pages and also woocommerce’s native product category pages). I re-entered the blocks and now the site works as it should.

While debugging I noticed that Woocommerce informs about a fatal error with the plugin in version 6.3.3:
