Thinkable X can't "Make Copy" no error, just nothing happens and no copy

Questions about Thunkable

I have sorted this type of error, it is usually a broken block. Now when I try to copy nothing happens, no pop up to say it has copied. A total blank and when I check there is no copy. I have completed a days work and don’t want to go back to this mornings version. Please help troubleshoot this.
