Hi @TonyCrane , Would you mind to help me to take a look at this issue? The `.tex` file was generated by manimlib, and here is the err log ```...

i met same issue, i think here is too many files in same folder will effect `createFile` speed. because before create file, it has to check item exists...

``` mUvcCamera.startPreview(new Surface(new SurfaceTexture(0))); ```

检查*.mk文件
