Cloning and soft block corruption

Hello All,

System:
RHEL8
Oracle 19.21 standalont to 19.21 cdb via clone.

We used cloning migration and we are continually getting below error. We are still in testing and will drop the PDB's before real cutover but its happening on a lot of different materialized views.
Yes, we have them set to no logging because it seems to build faster without the added overhead of the redo log.

ORA-01578: ORACLE data block corrupted (file # 1143, block # 771756)
ORA-01110: data file 1143:
'+DATA/TEST_INSTANCE/177E1F89EEDC7217E06322D6148CAC4A/DATAFILE/ts.606.1167922441'
ORA-26040: Data block was loaded using the NOLOGGING option

we rebuild the MV's and error goes away, a few days later it comes back.
