[Linux] HDRP Project crashes Editor with "(Unknown)" entries in the stacktrace when entering Playmode

Vulkan

-

How to reproduce:
1. Open the user attached project (StarLightLantern.zip)
2. In the Project window go to "Assets > Scenes" and open the "samplescene"
3. Enter and leave Playmode several times until a crash occurs

Reproducible with: 2018.4.27f1, 2019.4.9f1, 2020.1.4f1, 2020.2.0b1

Initially this was thought to be reprodubile only on Ubuntu with AMD/Intel cards but this is also reproducible on Windows. It also is not specific to AMD/Intel cards - the crash may or may not happen depending on how command pools are reused, and the crash is more likely to occur on GPUs that have a smaller amount of RAM.

    I can no longer reproduce this issue on Unity 2021.1.5f1
    (GPU: Radeon RX 5700 XT, driver: Mesa 21.0.3, OS: Fedora 34)

    Had the same bug with Unity 2019.4.18f1 and 2020.2.5.f1 to 2020.2.7.f1 on Linux Mint 20.1. Graphics Card is Radeon RX 570. Also what's weird is that the crashes occur far more often with a new/custom scene then with the standard sample scene in all versions i tested. If i modify the sample scene and enter playmode several times, it crashes mosty after the 4th time entering/leaving Playmode, sometimes not even then. With a new scene, Unity most of the time crashes after the first time entering or leaving Playmode, even if there is just 1 cube in the scene.

    I reproduced this bug with 2020.1.10f1 on Ubuntu 20.04 and Manjaro 20.1.2 using a Radeon RX 5700 XT.
