Product variation swatch image not showing.

https://www.loom.com/share/fba30a4a1f28490f9b0c706b837b2e0b

Hi, I recorded my screen, please check it a bit.

I installed the plugin, did the setting.
From woocommerce-> attributes I selected color attribute as images.

Then I created 1 variable product, gave all featured images for all variations, but it is not showing in single product page.

If I inspect it shows img source unknown.

Please help me out to solve this issue.
