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

When I try to make copy of project in Thunkable x, 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 which does allow me to copy.
Please help troubleshoot this.

Ok Thunkers. I found my issue. The “Make Copy” is working, it is just not telling me it is copying. And when I I sign out and look at my saved projects, it has saved it, not with todays date but a the 31st August, a month old date.
