I just had the same thing occur to me with the 2022 version.
I had my taxes just about complete. It was saved on the filesystem.
I opened Turbotax to complete my taxes and the it had a long update. Once the update was complete my Tax file was gone.
I know where to look and there are no .tax2022 files anywhere. The update definitely did delete my file.
This is a VERY serious bug. From now on, I'll make copies of my tax2022 files so the software doesn't cause me hours of work...
