Incredibly long load time on first launch

    On our HDRP 2019 LTS build we've been running into incredibly long initial launch times for users.

    This seems to only happen on their first launch, it happens before even getting to the splash screen, and nothing is displayed during this period. This can around a minute where nothing appears on the screen (except on Mac the mouse turns into the rainbow loading cursor). What's weird is that this is really only an issue on the first time they open our app. Seems to be more prevalent on Mac.

    Any suggestions, it's become pretty critical since many have thought that their computer was frozen and never make it to the fully loaded app since it takes so long to just get to the splash screen.

    Thanks!

    Found that this happens when building a blank HDRP scene in 2019 LTS as well.

    I tried the same process with unity 2021 (HDRP blank screen) and found that this was fixed. The build opened almost instantly.

    Is there a way around this besides upgrading to 2021? Upgrading our whole project to 2021 would be an immense project....
