Getting this error after installing unity-rlottie version 0.2.2:

Multiple precompiled assemblies with the same name System.Runtime.CompilerServices.Unsafe.dll included on the current platform. Only one assembly with the same name is allowed per platform. (Assets/Packages/System.Runtime.CompilerServices.Unsafe.4.5.3/lib/netstandard2.0/System.Runtime.CompilerServices.Unsafe.dll)

Multiple precompiled assemblies with the same name System.Runtime.CompilerServices.Unsafe.dll included on the current platform. Only one assembly with the same name is allowed per platform. (/Volumes/SamsungT7SSD/MyProject/Library/PackageCache/com.gindemit.rlottie@82e20a0008/ExternalDlls/System.Runtime.CompilerServices.Unsafe.dll)

Deleting one of the System.Runtime.CompilerServices.Unsafe.dll files did not work, any advice?

Unity version: 2021.3.19f1

Hello @Rica02, thank you for your report!

Could you please provide some details about your installation process for the Assets/Packages/System.Runtime.CompilerServices.Unsafe.4.5.3 package? This will help me to replicate the issue on my end.

Additionally, you mentioned attempting to delete the Assets/Packages/System.Runtime.CompilerServices.Unsafe.4.5.3 package. I'm curious - once the package was deleted, did you encounter any subsequent errors?

We believe it's from Microsoft's NuGet library (https://imgur.com/a/kKmKrOA). Deleting its Unsafe package caused compiling issues with the library we're using from it

Hello @Rica02, thanks for the infos!
I think I will remove this dll in the next release from the package.
The projects that does not have the dll awailable will need to install it separately.
