Server error sending from bc1... address

I can’t send my BTC. I attach the error message.
What can I do?

Error making request to UNKNOWN/Default: JSON-RPC Error:

Type: Server error

Code: -32000

Message: Bad status code returned: ‘500’. result body: '{“result”:null,“error”:{“code”:-26,“message”:“64: non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation)”},“id”:0} '.

I’m getting the same error.

Was your issue ever resolved.???
