IDE Plugin - Unable to open web browser in File Editor window

I used to be able to open a website within the Editor window, but now it only opens as a white screen in a new tab. This is on 2023.2 Ultimate edition

VirtualFile virtualFile = VirtualFileManager.getInstance().findFileByUrl(recommendationUrl);

Url url = Urls.parse(recommendationUrl, true);
WebPreviewVirtualFile webPreviewVirtualFile = new WebPreviewVirtualFile(virtualFile, url);
FileEditorManager.getInstance(project).openFile(webPreviewVirtualFile, true);

return FileEditorManager.getInstance(project).isFileOpen(webPreviewVirtualFile);
