Not able to create New product and new page

Hello,

I have installed woocommerce import export order plugin, i have used it and after a day i just deactivated the plugin. As i deactivate the plugin neither my new product page is working nor new page. When i click on new product page ot says “this page is not working” same error for when i attemp to create new page. Everything else is working.

Can someone please help as i have no idea why this is happening and how i can resolve it.

Any help would be appreciated.
