Hey everyone, I thumbed through some of the search results on this forum for the above error but couldn’t find anything conclusive. What is this error and how do I troubleshoot it? I’m not sure if it’s something to worry about or ignore. There aren’t any actionable buttons provided other than “Close”.

There aren't any actionable buttons provided other than "Close".
it is just a scan error warning, not a detection so not something avast would take any action on ..... so no buttons to press

seems to be a file path that is not correct … if you reboot and scan again, still the same?
