A fix for this will be available in the next core update which should be released in the next week or two.
In the meantime, if you have a project that crashes when you attempt to load it then you can either submit it here and I will fix it, or you can follow these steps to fix it yourself:
- Make a backup of your Flowcode FCFX/FCSX file
- Open the file in a text editor and scroll to the bottom
- Look for this: PinState='1' IsMaximized='0' IsVisible='0'
- Change it to: PinState='0' IsMaximized='0' IsVisible='1'
- Save your modified file
