Multiple precompiled assemblies with the same name Nethereum.Contracts.dll included or the current platform

Unity prompts that there cannot be two DLLs with the same name. However, if I try to delete either, it will result in an error

Unity logError:
Multiple precompiled assemblies with the same name Nethereum.Contracts.dll included or the current platform. Only one assembly with the same name is allowed per platform. (../mud-template-unity/packages/client/Library/PackageCache/com.emergenceland.unimud@555dfde4e7/Plugins/Nethereum.Contracts.dll)

There is also a Nethereum. Contracts folder in the Plugins folder of Assets

Are you using any other web3 packages in the project?

[hymDavian]

Currently, this program has only been opened through Unity2020.3.3 version, and no other actions have been taken yet

Would recommend you upgrade to the 2022 LTS version of Unity, not getting this error on a fresh install

I have upgraded my engine to 2022.1.9f1, but this issue still occurs

But.In the 2022 version, I deleted these two DLLs with the same name in Assets and will not report any errors
