i know that the cause is WD\WarehousingCreditNote\Block\Adminhtml\Warehousingcreditnote\Edit\Form should be WD\WarehousingCreditNote\Block\Adminhtml\WarehousingCreditNote\Edit\Form

but i don't know where to fix that, the namespace of the class itself already correct.

i've already tried to run php bin/magento setup:upgrade && php bin/magento setup:di:compile

rm -rf var/generation var/cache var/page_cache var/di

php bin/magento c:c php bin/magento c:f

but still no luck

any idea?

Go to /var/www/wd-magento/app/code/WD/WarehousingCreditNote/Block/Adminhtml/Warehousingcreditnote and rename the folder. You may need to rename it to WarehousingCreditNote1 and then rename it again to WarehousingCreditNote (since some servers are case insensitive).

Also, open /var/www/wd-magento/app/code/WD/WarehousingCreditNote/Block/Adminhtml/Warehousingcreditnote/Form.php and check the namespace case

You should also do a search for 'Block/Adminhtml/Warehousingcreditnote' to make sure you are using the correct case in all places
