I made it work, You need to go to Plugins > Plugin editor
then in the top right corner , in the drop down menu, select > Wpforms and hit Select
then a code editor will open and you need to got to line number 39 , it will say
update_option( 'wpforms_license', [
'type' => 'basic',
'key' => 'valid',
'is_expired' => false,
'is_disabled' => false,
'is_invalid' => false,
] );
you need to replace the 'basic' with 'pro' as shown in picture below
after doing this, you need to click on "update file" in the bottom left.
It works for me, for Addons, you need to update addon.zip throuh plugin installer and activate it.
Done
