I have configured and created some product on borsche, if I switched to another theme my product data of borche theme will be lost?
Your products are created using the WooCommerce plugin and are stored in the site database. Changing the theme should not cause any of your products to be lost.
That said, you can install the Health Check plugin on your site to view it with a default theme without it affecting the live version of your site that visitors can see:

I have deactivated the jetpack plugin and see the result.
Seeing what your site looks like with Jetpack disabled does not help us troubleshoot what’s going on here, as all that does is prevents us from seeing the issue.
Please test if enabling Jetpack, but using a different theme makes any difference, so we can rule out a conflict with your theme as a cause here.
While you have the Health Check plugin enabled, also check if it makes any difference if you disable all other plugins except Jetpack and WooCommerce. I can see a large number of plugins installed on your site, and any one of them could be potentially causing a conflict with Jetpack on your site, resulting in the images not loading.
From the data Jetpack has for your site I can see you’re using the W3 Total Cache plugin and also the Revslider plugin, for example, and both those plugins are known to cause issues with Jetpack. Revslider in particular has a known conflict with our image CDN:
