Can't Save or discard Untitled* Version 6.2.6 for Firexfox

This bug is so annoying.
It auto open a Untitled* and also block switching to all other actions.
Everything work fine in Local Browser.
I’m using it on Firefox Portable 90.0.2 (64bit) → Mozilla Firefox, Portable (browser) | PortableApps.com
and Windows 10 (64) latest

What does this mean?

What happens if you click “Cancel”?

After Click Save or Cancel it blocks switching to all other actions and just stay there!

And what is this?

I think you have a non saved macro code, save it and solve the problem.

Apdate to the latest ui vision version please, you’re using 6.2.2
