FYI dotnet/linker#729 (comment)

[alexkeh]

The symptoms are the same as this issue: #42

It's the same error, package assembly, and stack.

That bug has been fixed already. If you have access to My Oracle Support, the patch can be requested as a one-off or you can wait until the next bundle patch is released.

The ODP.NET team hasn't decided when to release the next NuGet package. We just released 19.5. The fix should be in the next NuGet drop.

I tried 2.19.60 and confirmed that this issue fixed. Thank you @alexkeh !

2.19.60 compiled successfully but found another issue at runtime.
