I just updated to 2.2.0 and now I'm see this error on launch in Unity Editor WebGL platform.

Sentry: (Error) Failed to persist session on the file system. System.ObjectDisposedException: Cannot access a disposed object.

Looks like the same problem reported here

• Console shows error when launching game in the editor #1841

[bruno-garcia]

cc @jamescrosswell did we change something in the core Sentry package that could cause this?

[bruno-garcia]

The diff in Unity is here: 2.1.4...2.2.0

Bit it's most likely caused by some change in the .NET SDK, possible either:

• Fixes "Failed to persist session" error on iOS sentry-dotnet#3655

Or

• fix: Route file writing through FileSystem sentry-dotnet#3614

Confirming that WebGL is in the KnownPlatforms:

sentry-unity/package-dev/Runtime/SentryInitialization.cs

Line 296 in 8966aaf

platform == RuntimePlatform.WebGLPlayer

So it should have file I/O enabled

[bruno-garcia]

OK so @jamescrosswell figured out:

He fixed this problem in this PR:

• Fixes "Failed to persist session" error on iOS sentry-dotnet#3655

We bumped it in this repo. but that fix wasn't included in the last release.. It has been sitting on main so I just triggered a release now.

It'll be version 2.2.1

The released 2.2.1 addresses this issue. Please feel free to reach out if you're running into any troubles.
