Blazor Cant load image, has been blocked by CORS policy, even tho i allowed any header any origin

I have an application where a js script inside has to put markers on a map, this icon comes from a folder on my api, any other image that is loaded inside my blazor load properly but when i load the image from my Js it says cant load resource cause of CORS.My js code

addMarkerToGroup(group, { lat: partner.lat, lng: partner.long }, `${partner.id}`, new H.map.Icon(partner.icon));

My api program.cs

app.UseCors(builder => builder.AllowAnyOrigin()                .AllowAnyHeader()                .AllowAnyMethod());

Does anyone know how i can fix this issue.Thank youAn desperate student
