Uncaught TypeError: Cannot read properties of undefined (reading 'bootstrap-input-spinner')

[dheeraj-ashokan]

Hi, I'm working on an Escape Game kind of website.
I am using the ESCAPE theme by Themecube from Envato.

So for booking, I'm using the Woocommerce Booking plugin and while selecting the date from the calendar, the date picker feature is not working.
I'm getting the above error on the console.

The plugin is working fine with the WP Storefront theme.

I'll attach the screenshots for your reference.
Any leads to the solutions are much appreciated.
