Importer (-1,00000000000000000000000000000000) Killed

**Bug description**

Hi, I am using the [default config](https://gitlab.com/game-ci/unity3d-gitlab-ci-example/-/blob/main/.gitlab-ci.yml) on Gitlab CI and I am getting an importer error.

```
Start importing Assets/Procedural Worlds/Gaia/Lighting/Content Resources/Skyboxes/PW_Sky_Evening_Clear.hdr using Guid(17e01958f958b3469b23dfe8cfdca48f) Importer(-1,00000000000000000000000000000000) Killed
Cleaning up project directory and file based variables
00:03
ERROR: Job failed: exit code 1
```

The `hdr` file is `33MB` and is failing to import on all builds (OSX, Linux, WebGL, ...)

I unfortunaly don't have more logs than that.

**How to reproduce**

The HDR file is coming from Gaia Pro.

Create a new project, configure Git and the CI, install Gaia Pro, commit and push.

**Expected behavior**

It should correctly import the HDR file

**Additional details**

The build is failing with `unityci/editor:2021.3.2f1` and `unityci/editor:2021.3.4f1`
