您的Unity项目中使用了不支持WebGL的插件或库，例如dlopen函数。这会导致在运行时抛出异常，并显示错误信息。要解决这个问题，您需要检查您的项目中是否有使用这些不兼容的功能，并尝试替换或删除它们。
您的Web服务器没有正确配置响应头，导致浏览器无法正确加载WebGL构建文件。这会导致在加载时出现错误，并显示错误信息。要解决这个问题，您需要确保您的Web服务器能够支持WebGL构建文件的压缩格式，并且能够正确设置Content-Type和Content-Encoding响应头。
您的浏览器不支持WebGL或者没有启用WebGL功能，导致无法渲染WebGL内容。这会导致在运行时出现错误，并显示错误信息。要解决这个问题，您需要确保您的浏览器版本能够支持WebGL，并且在浏览器设置中启用WebGL功能。有关更多信息
