频繁 load ResourceManager 中的资产，很容易出现设备丢失（案例代码无法复现）

请问引擎版本和运行环境分别是什么，复现步骤是重复调用 changeGlb 吗。

[MrTangmx]

"@galacean/engine": "^1.0.4" "vue": "^3.2.47", node 16.16
是的

[MrTangmx]

threejs 会不会和galacean/engine发生冲突，目前看来好像是内存被吃完了

[cptbtptpbcptdtptp]

同时运行 threejs 与 galacean 吗？在你的环境中如果不重复调用 changeGlb 是否会有异常。
