Finder search results disappear, then reappear
I'm using the regular Finder search to try and locate files on my computer and on an external hard drive. I've worked around this problem in the past, but now I really need to find a file and this is a problem.
When I search, the results come up. They last for a few seconds while I scroll through them and then they just disappear. Usually they don't come back. Once, changing USB-C ports seemed to work, but not anymore. Now I'm trying to find some files from last October and it requires me to scroll through. All of the results disappear after a few seconds. Then they reappear but it brings me back to the top. So I don't have time to scroll through them and find what I'm looking for.
Anyone have any suggestions?
