For completeness, see below. After reinstalling FastRawViewer, restarting Windows, and restoring the preferences, the issue went away. But I'm also now running the machine without the eGPU. It is currently only with the internal Intel GPU. At the moment I cannot do further tests because the eGPU is not detected anymore. Possibly the Thunderbolt ports in my machine are flaky again. So, for now, the issue is solved, but it may resurface once I get the eGPU running again.
