Lol, I know. The WooCommerce Product Edit Screen was blank with the error below (which broke the product tabs)

Fatal error: Uncaught ArgumentCountError: Too few arguments to function product_custom_tab::product_tab_options(), 0 passed in wp-includes/class-wp-hook.php on line 286 and exactly 1 expected in /wp-content/plugins/woo-product-tab/includes/product_custom_tab.php:64 Stack trace: #0 wp-includes/class-wp-hook.php(286):

When going to line 64 of product_custom_tab.php. I changed

public function product_tab_options($product_type)

to

public function product_tab_options($product_type = null)

And it worked! Thanks to the contributors below! You really made my day. Thanks for being here. Thank you!
