Every time I try to make a transaction using my gmail derived sui wallet I get the following message. This has happened across numerous different apps. See below for error message.

“Transaction validator signing failed due to  
issues with transaction inputs, please  
review the errors and try again: - Balance of  
gas object 3658936 is lower than the  
needed amount: 10920416 - Signature is  
not valid: Signature is not valid: General  
cryptographic error: JWK not found” there is also a link at the end
