Honored ContributorBased on what I see in the error.bmp it is failing on download.
SBT download the elf file, but on verification, it could not confirm that the correct data was downloaded into the onchipmem. Most likely this happens when your design does not meet timing. Since you mentioned that it was working, then what I can think of is change of temperature, FPGA get heated up, device broken, and so on... You might want to double check the board setting as well. If you are using correct source of clock, power is given correctly, etc.
