Here the is dbg information what i can do.....
From a first glance, I would say you are missing the database driver (mysql library/dll).
The IDE attempts to open your last project, and that probably has a db component on the form.
It then runs into an exception
UNRESOLVED BEFORE loading 0 Root=FormFolsDocs:TFormFolsDocs RefRoot=MainForm Refs="MySQLC
SQLT"
To resolve that you probably need to put the required dll into the IDE folder.
But it may also be, that you have to rebuild the IDE once.
Packages are installed by building them in the IDE (we know dynamic would be welcome, at least by some users, but does not exist yet)
So when you upgrade, the IDE needs to be rebuild once, to get all packages back again (they are still in the list of installed, so only rebuild, no need to install them all again).
You can open your IDE with (properties of shortcut)
--skip-last-project.
Or temporary move the last project to a different folder, so the IDE can not find it.
