Sharing a report from another user but should be investigated ASAP.
When uploading his signed PSBT, using a micro SD, from his ColdCard Q to Caravan, he received the message. Signature for input 4 is invalid. CCQ firmware was up to date. His trezor was able to sign in caravan.
He tried again with Sparrow, and it was successfully uploaded.
EDIT (10/3):
I did not clearly describe the signed PSBT bit here. This was for signing with a coldcard which has an "upload psbt" step, but it wasn't with the import psbt for tx creation that would happen on the first step.
