You're welcome. I'm glad if I've been able to be of some assistance. I'm sorry I don't have a good answer to the problem you're experiencing. Hopefully someone else here on the forum will join in with some idea.
If you have any other device you can configure as an access point or hotspot, turn that on to see if that will be detected by ScanNetworks. Or if you can take your MKR WiFi 1010 somewhere where you can run it in range of other WiFi routers, try that. If you can get ScanNetworks to see another device, then that will indicate the problem is something specific to your WiFi router, rather than a general issue with the MKR WiFi 1010.
