LoadStoreError on OTA

[poengAlex]

Hi

I have some trouble with using OTA (about 1Mb bin) in a task. I use the “AWS S3 OTA Update” example in Arduino as a base and run it in a task (runs on APP core, changing priority and stacksize does not help)). Sometimes the OTA is successful sometimes it crashes at random percentage and I get this error:

Any suggestions on whats wrong? And what is the LoadStoreError?

Thanks!
