can happen and can be repaired in some cases by:
direct XAML editing
In some cases a remodelling is needed, but before this we recommend to define a modernization strategy and also check if FTS branches are really the choice of used versions. Maybe LTS branches should be the targeted version levels
If you delete the project.json file and try reopening the Main.xaml file with UiPath Studio, it will attempt to open with the latest packages. This may automatically resolve package incompatibility. (Of course, be sure to back up the project.json file first.)
Gradually upgrade the relevant packages. For example, if a package version is 22.4.4, start by upgrading to 22.4.5 first. Then proceed to 22.4.6 and continue upgrading to the desired version incrementally. Transitioning between packages with minimal differences in versions will be easier.
If your goal is not to upgrade to the latest version for all packages, you can open the project.json file with Notepad and manually update the dependencies section with the package versions used in the project before the upgrade. Then try opening the project with UiPath Studio.
