MATLAB: Problem with App designer 2019a

2019aappdesignerMATLABmissing componentsmissing inspector

Hi!
After installing 2019a (had 2017b earlier) the appdesigner is no longer working. Buttons and stuff are missing in my old apps and also if I try to make new ones. The inspector panel is missing and I get the error:
Error using matlab.ui.control.internal.model.mixin.MultilineTextComponent/set.Text (line 49)
'Text' must be a character vector, a 1-D cell array of character vectors, a string array or a categorical array.
