Earlier I faced that issue,it will be solved by appending a tag after opening a new tab

this.http.get(`url`)
    .subscribe((response: any) => {
        const filePath = 'data:application/pdf;base64,' + response.data;
        const aTag: any = document.createElement('a');
        const fileName = response.name;
        aTag.href = filePath;
        aTag.download = fileName;
        window.open(filePath, '_blank');
        document.body.appendChild(aTag);
        aTag.click();
        document.body.removeChild(aTag);
        window.close();
    }, (error) => {
        this.notificationMsgService.errorHandler(error);
    })
