i've come across the same thing using StringAsset and AssetArchive for aws lambda functions here:
<https://github.com/pulumi/pulumi/issues/7076#issuecomment-843558455>

basically, it seems like the `pulumi refresh` operation does something to change the state that breaks serialization. so for me the temporary solution is to just never run `pulumi refresh`

I am not using any pulumi refresh. Just using pulumi up. Still getting the same issue.
