You could erase its non-volatile memory which is almost certainly the region that's got some minor corruption. It's not something to do lightly and you absolutely should NOT try it without making a safe backup beforehand. Make the backup of it with "rrgn" command then erase with "ergn". As the region's data will be encrypted there is no easy way for you to check the viability of the backup so maybe make it a couple of times before erasing. If you try the erasure please understand that it's done on the firm basis that it's entirely at your own risk. I do regard it as a method of last resort personally but cannot think of anything else you can try that might be helpful. If it makes no difference then you can write back with "xrgn" command.

Your device probably has NV in rgn154 rather than 41 however some devices may have copies in both but usually if one is populated the other in empty. [Only registered and activated users can see links. ]
