Sudden errors components temporary solve by deleting and reintroducing same code

[HansHeintz]

I opened my app for editing and found it suddenly contains hundreds of errors. They all relate to self made components. Opening the errorlist I find they specifically relate to properties of components like onreset. If I go by them one by one and delete this code in the component (cut) and then reintroduce (paste) the errors go away. But if I save and reopen they are back.

If I open a version of my code from before the problems, like 10 versions back (reset version) there is also this same problem that was not there when I opened this version before.

The code is mostly simple like in a onreset: reset a textinput and set a variable

I did recently copy components from this app to another app but I would not think there is still some connection between them and also I did not change them in either app.

What could be happening?

Just found out it's some huge unsolved bug in european versions:

There are also workarounds here.
