If I understood, your OKUMA frozen o this message: SBP Versio e7.
If it is so, looks like bubble memory is broken. But please check all power supply in the electrical cabinet. Make photo of power supply unit after the lathe will be frozen. May be some of supplu (+5, +12 of other) broken.
I destroy me bubble memory after one of my power disappeared. The sequence of voltage in CPU unit is strict. And wrong sequence can destry data in memory. It was my lathe. After that I changed the CNC to China.
It was more cheaper then repaire machine, but I lost accurace.

Could be service board processor as well , good idea to reseat the boards and any “socketed” chips as well. Sometimes connection becomes bad and causes communication alarms like you have.
