SQL Navigator 7.6/8.0 high CPU/Memory usage

Recently acquired a new laptop (windows 11) and for some unknown reason, SQL Navigator is resulting in extremely high cpu/memory usage. Tried both 7.6 and 8.0 versions. Also, completely uninstalled and reinstalled but didn't help. Navigator starts fine but as soon as start a session, both memory and CPU usage creeps up. Even in idle condition, CPU is continually around 30% and memory goes up to 10GB or higher until laptop becomes unresponsive. Any suggestion to solve this would be appreciated.
