BDK Native not working (White screen)

Good afternoon, I hired the BDK Native service and plugin and the application simply does not work (white screen).

I tried to contact the plugin owner, we tried a few times but the problem was not resolved. It’s not a problem with Bubble because it works perfectly well on the web…

I tried to contact you to request a refund but I haven’t responded for 4 days. Does anyone have any suggestions on what I can do?
