UE4 断言在 opengles.h 失败，但我知道 ue4 可在我的设备上运行。怎么解决？

Question

我可以在我的设备 sm-j700m samsung Galaxy j7 2015 上运行 PUBG MOBILE（以及 LITE 版本）。
Pubg 使用虚幻引擎 4！
这里安装的UE4编辑器版本：4.26.2

在项目设置中有一个启用的选项“支持 OpenGL ES3.1”。

此链接中的一些引擎代码，准确显示了问题发生在 check() 处：
https://forums.unrealengine.com/t/4-25-apk-runs-fine-4-26-1-apk-crash/158698/4

static FORCEINLINE void ColorMaskIndexed(GLuint Index, GLboolean Red, GLboolean Green, GLboolean Blue, GLboolean Alpha)
{
if (bSupportsDrawBuffersBlend)
            {
                // ES 3.2 or extension
                glColorMaskiEXT(Index, Red, Green, Blue, Alpha);
            }
            else
            {
                check(Index == 0);
                glColorMask(Red, Green, Blue, Alpha);
            }
        }

日志中还有其他内容可以帮助解决此问题吗？

因此“LogRHI：应用程序已针对 OpenGL ES 3.1 进行打包，并且检测到支持 ES 3.1 的设备。”意味着它应该可以正常工作吗？

按照建议（https://forums.unrealengine.com/t/4-25-apk-runs-fine-4-26-1-apk-crash/158698/7），我是否必须重新编译编辑器（在我的 4 核上花费了 +12 小时）删除该断言还是有一个创伤较小的选项？

您认为他们删除了 pubg mobile 的断言吗？
我看到有很多断言可能仅在 OpenGLES.h 上失败，所以我宁愿不修补引擎，除非这是唯一的选择，因为重新编译需要很长时间。

我在 UE4.27 上遇到了完全相同的问题。你成功解决了吗？还有希望吗？？？
