The short answer is yes. There is an issue with the new SWR foldback feature that is affecting a small percentage of users with certain amps and autotuners. We are actively testing a fix to the SWR foldback issue. Initial testing is showing promising results and the fix should be included in the next release of SmartSDR for Windows.
If this issue affects you, as previously noted, reverting back to the previous version of SmartSDR is the recommended course of action until we have the issue resolved.
