AT+SYSMFG read command response throws error where AT+SYSMFG write command responded OK

[Kavya S]

I am trying to use NVS AT command to store some data of less than 1kb in ESP32WROVER in communication with STM32H7 controller, On trying i received ERROR while NVS read command is executed. I have used the same ESP with same commands mentioned below without any changes 6 months back, at that time I haven't faced any issues, now I am trying to do the same I am getting issue.
The set of commands I have used:
AT+SYSMFG=0,"work","name"
The above command I have used to erase, and received ERROR.
AT+SYSMFG=2,"work","name",8,8
The above command I have used to write, and received OK, followed by >, After receiving > I sent my data "teams1.1" for this I received busy p... following it I received OK.
AT+SYSMFG=1,"work","name"
The above command I have used to erase, and received ERROR.
The same commands I have used 6 months back and everything works fine, but now it is throwing ERROR.
Could you suggest the solution to fix this issue and what could be the cause for this issue?
