It looks like you have a corrupted file. Try loading the last backup, which should be named something like rob-gnucash.gnucash.20200405154732.gnucash; the numbers in the middle are a date stamp, yyyymmddhhmmss, for the subsequent save. Depending on what work you did in the last session you may be able to recover some of it by replaying the corresponding log file with File>Import>Replay log file.

You should also check the drive with `chkdsk` and `wmic diskdrive get status` to make sure that the corruption was something random like a cosmic ray and not the first sign of needing a new one.
