This error is indeed due to the Salesforce Winter ‘26 release. This update from Salesforce has caused the old pre-v22 DBAmp to fall out of compatibility with the Salesforce API.

 

The only fix for this issue is to upgrade to the latest version of DBAmp:

I had the same error after Salesforce Winter 26 upgrade.  Maybe this will help you:
