Updating Integration Service Activities to 1.5 breaks (again) project

Im posting this here for the sake of PUBLIC KNOWLEDGE, as I already opened a ticket.

After updating Studio (to 2023.10.6), I saw a update from the Integration Service Activities to 1.5.

As that activity type for the output variable of Get Record for async Teams operation is giving a problem (and it’s the subject of another open ticket), proceeded to update also in another prject I have for a Library.

When updating, it broke the project.

This happened before with other projects and I already reported this on the bugs forum and you were supposed to address these kind of things before.

Moreover: after that, if I exit Studio without saving anything, in an attempt to undo the damage done, it’s of no use - on restart, the problem will still exist there.

If I try to downgrade again back to version 1.4 of the activity, the error stays the same: my project is broken, I don’t have a copy of the previous broken one, and I can’t even compare what was there that I have to recreate in the new one. That’s not fair.

I don’t find acceptable for a 5-figure paid software like this that updating breaks our working projects.
