I agree with @ABCbits your electrs (and core) are both out of date. We are talking about your money here why run software that is so far from current?

Also run smartctl  (or similar) on the disk that is holding the data to make sure that it's not drive related.

What hardware (and how old) are you running it on. Just because you can install and run it all on a 4th gen i3 does not mean you should.....
