Unhandled Exception: System.TypeAccessException: Attempt by security transparent method 'Google.Protobuf.ByteString.CopyFrom(System.ReadOnlySpan`1<Byte>)' to access security critical type 'System.ReadOnlySpan`1<System.Byte>' failed.
Assembly 'Google.Protobuf, Version=3.12.3.0, Culture=neutral, PublicKeyToken=a7d26565bac4d604' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.

at test1.Program.NewMethod() in D:\Dev\test1\Program.cs:line 11
Anything else we should know about your project / environment
Same issue as "Can't call ByteString.Span on net45 #7139".
Tested putting the [SecuritySafeCritical] on CopyFrom. This solved the problem:
#if GOOGLE_PROTOBUF_SUPPORT_SYSTEM_MEMORY/// <summary>/// Constructs a <see cref="ByteString" /> from a read only span. The contents/// are copied, so further modifications to the span will not/// be reflected in the returned <see cref="ByteString" />./// </summary>[SecuritySafeCritical]publicstaticByteStringCopyFrom(ReadOnlySpan<byte>bytes){returnnewByteString(bytes.ToArray());}
#endif
