Forum help for author's lack of assistance

Hello everyone, I hope to find someone to help me. Unfortunately, the creator of the template I bought does not respond to emails (even if the 6 months of assistance have not passed) and I don’t know how to do it. Some of the portfolios of the theme give problems in the sense that when I put the site online the images are no longer seen while I work on worpress, everything works perfectly. I tried to deactivate the plugins, maybe it’s elementor but I’m not an expert and I don’t know how to do it, maybe go back to old versions of elementor? The theme is created in November 2020. I leave here the links of the theme and the author. I really hope someone can help me it’s really a big problem for me…
Envato told me to ask you for help… please help me!

Sorry to hear that you’re having issue with the theme but support should be provided by the author. If you’re unable to get some support by them, most likely, what we can offer is a paid support/job as this is beyond helping. In case, you can purchase a service from my Studio account - I’d be happy to help you.
