Also started to receive this message with upgrade to 30.0 on Windows 11. Mapped network drive in Windows is to SMB share on a NAS on a LAN; I have been using same configuration of workstation and NAS with Illustrator for years without receiving this message. Both machines successfully sync time regularly with a local timeserver on the LAN.
Edit adding: it's not every file. For instance: two files open on same share, one saves changes normally, the other gives me the message with every change. If I find a pattern, I'll post it here. Save and reload the "problem" file, then seems to save normally. Then another file which was saving fine starts to show the message...
