Unity Loads for 2 minuites every single time play is pressed.

[pineda1000]

We are working on a huge project.
100k -ish files

Every single time Play is pressed on unity editor it hangs for around 2 minuites.

I tried to isolate the issue.

steps i tried.
1.) I moved from version 122 to version 150.
2.) unchecking everything that i can uncheck in the settings.

I also tried to disable every dll. in the folder. aside from the
Google.VersionHandlerImpl

it still loads for an unacceptable amount of time.

This however does not happen when i try it in a empty project.

I also are unable to profile on what in the DLL's are triggering this massive spike in loading time. as the calls in a DLL does not show up in a profiler.

I can now fix the issue by importing the ExternalDependencyManager once in a while when building, and disable them after...

UNITY VERSION 2019.3.X

Hi, I think I have the same issue. Initially, I thought it was firebase dependencies, but I think it comes from the dependency manager.
Here is the result of running the profiler in Editor mode, this is caught in one of the first frames:

In my case, this IOSResolver is taking about 50% of the startup time. Note that I'm running on windows and building for android. So I don't understand why IOSResolver needs to run here.

I'm also having this problem, though for me the slowdown occurs in generate_xml_from_google_services_json.

It is the dependency manager. Removing it resolves the issue, though of course then you can't use Firebase because it has a dependency on the resolver. I'm currently working my way back from 6.13.0 on the Firebase Unity SDK to find one which includes and relies on a version of the dependency manager where this slowdown doesn't exist.

I have the same problem. Not only entering Play mode causes this issue but every compilation for me. Verbose Logging shows a lot of iOS-related stuff going on. I'm on Windows, building for Android. Unity 2019.3.9.

Here they talk a bit more of why this is happening.
It would be really great to take those validation the resolver do. It's making the development process really hard.

Happens every time when entering play state. Adding -gvh_disable to command line and turning everything off from settings does not fix the issue. Only choice is to delete whole folder until those static constructors are fixed.

I'm also experiencing massive slowdowns on entering the playmode. (And sometimes just beeing in the editor as well)

Using EDM + Firebase Plugins

Deleting EDM + the firebase editor folders solves the issue for me.
I'm still keeping them in my git in case something is ever needed.

We are too started experience lockdowns on start after installing Firebase + EDM.

We are experiencing the same behaviour on our projets. It is slowing grinding our working hours for nothing.

[miv]

So, this is actually two-fold problem! It is EDM and it is Firebase plugin. Both are slowing down DRAMATICALLY.

We've removed firebase and edm from our manifest.json and adding edm and firebase on build servers (by copying separate manifest on top of main one), putting all firebase code behind compile time define 🤦🏻‍♂️

The change in speed incredible - we were having 10 seconds hangups on every Play, now play start instantly.

[igor84]

For us the main problem is in Firebase.Editor.dll which calls python process on every recompile and when entering play mode. This call takes 10 seconds on its own. Then another 5 seconds are added by IOSResolver, PlayServicesResolver, GPGSUpgrader. Waiting for 15 seconds after each compile and when entering play mode is killing us.

[MartinGonzalez]

Sadly this is happening too in every project we have firebase. And we can confirm too that is Firebase dependency what is causing this.

This is REALLY annoying and it's complicating our development process. If we can help in anything please let us know, but we need to reduce this time.

[jimanjr]

Can we please have ANY update from the Firebase team? This wastes hours of development for every team member.

This issue is also related I think: firebase/firebase-unity-sdk#378
