Retrieving netstandard API reference takes forever (hanging)

I'm using the prismicio.netstandard library from the nuget package in a server-side blazor app. For some reason, when I try to get an API reference using the "DefaultPrismicApiAccessor" class, the call to the GetApi method never returns.

I was able to get it to work once only, but after that is just stopped working.

I'm not sure if I'm using the library incorrectly as I am new to prismic, and I haven't been able to find any good examples/documentation on how to use the prismicio.netstandard library. I also tried using the older "prismicio" nuget package, but that has the same result, getting an API reference just hangs.

Here's my current code:

        private prismic.Api PrismicAPI
                if (_apiAccessor == null)
                    var cookieContainer = new CookieContainer();
                    var httpClientHandler = new HttpClientHandler
                        AllowAutoRedirect = true,
                        UseCookies = true,
                        //TODO: CheckCertificateRevocationList = true,
                        AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip,
                        SslProtocols = System.Security.Authentication.SslProtocols.Tls12 | System.Security.Authentication.SslProtocols.Tls13,
                        CookieContainer = cookieContainer
                    var httpClient = new HttpClient(httpClientHandler);

                    var httpClientLogger = _loggerFactory.CreateLogger<PrismicHttpClient>();
                    var apiLogger = _loggerFactory.CreateLogger<prismic.Api>();

                    var httpContextAccessor = new HttpContextAccessor();
                    var memoryCache = new Microsoft.Extensions.Caching.Memory.MemoryCache(new Microsoft.Extensions.Caching.Memory.MemoryCacheOptions());
                    var inMemoryCache = new prismic.InMemoryCache(memoryCache);
                    var prismicHttpClient = new prismic.PrismicHttpClient(httpClient, inMemoryCache, httpClientLogger);
                    _apiAccessor = new DefaultPrismicApiAccessor(prismicHttpClient, apiLogger, inMemoryCache, httpContextAccessor);

                //this call hangs and never returns:
                var prismicAPI = _apiAccessor.GetApi(apiEndpoint, permanentAccessToken).Result;
                return prismicAPI;

I would appreciate if anyone have any suggestions/recommendations on what may be wrong here.
