CRC errors after reprogramming ADV7619

when reprogramming the ADV7619 chip during operation, it happens that after reprogramming lots of CRC errors occur. This happens on all boards and in approximately 1 test run out of 10. I see this error popping up when the case temperature of ADV7619 is 50 dgrs C or higher. Cooling down the ADV7619 (coldspray), reprogramming ADV7619 with the same sequence & settings solves the issue. No CRC errors occur anymore even if I let the case temperature raise to close to 70 dgrs C.

Did someone see similar effects with this chip / is this a known issue? Can the root cause be register settings / programming sequence?
