sitemap_products_1.xml returns 500 error

[ninjabenja]

My sitemap is genereated here. 

https://www.gamescape.com/sitemap.xml

The link to sitemap_products_1.xml returns a 500 error when accessed.

https://www.gamescape.com/sitemap_products_1.xml?from=5656878612643&to=7728378183843

Google Search Console also reports that it can not fetch the sitemap_products_1.xml file. What can I do to resolve this issue?
