We got the same error. We had to force the previous version with -MaximumVersion 4.1.120

Same issue when trying to install from the PowerShell Gallery.

Thank you for the report, we're investigating.

Version 4.1.121 of AWSPowerShell.NetCore does have a valid signature if you need to stay on the latest version and are able to switch modules.

4.1.121 of AWS.Tools.Common is impacted also, which therefore impacts all of the AWS.Tools.<service> modules.

We just published version 4.1.122 to PowerShell Gallery, which was signed with a root certificate which is trusted on Windows.

We also just unlisted 4.1.121 from PowerShell Gallery to try to avoid additional users from stumbling upon this. Sorry about the inconvenience.
