Edge Client Configuration Data Corrupted

I haven't gotten into any real troubleshooting process yet since it only came up from a user yesterday and I had only seen it once before about a week ago, but I will definitely include that as a step to try. We only have a few people with the edge client now, just a small pilot group in IT mostly.

If the problem is still in 11.6 then I don't guess upgrading will help me there. I am tempted to set the config.f5c file to read only, there is no reason for them to change anything in and I really don't even want them looking at it. I am not sure why it would get corrupted, but maybe this will block that from happening.
