Hey guys,

i wrote a little application with pyqt5 and it worked fine. But today suddenly i can't run the application. I get the following error:

Traceback (most recent call last):
  File "C:/Users/hrezaie/Desktop/Hamid Rezaie/GuiApp/GuiApp/app.py", line 768, in <module>

    self._root = parser._parse_whole(source)
xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 1, column 1

Process finished with exit code 1

@elias_hh Are you parsing a XML document in your app? Is this document still valid XML?

[elias_hh]

@jsulm Hey, no i dont use any XML document. I think the problem is my .ui file. Because if i want to open it with qt designer i get suddenly a error message to.

[jsulm]

@elias_hh So, check the content of that ui file

Hi
What was it ? Just so others might also be able to fix it.

[elias_hh]

@mrjj hey, unfortunately I didn't solve it in a nice way, but simply recreated the gui again. Afterwards it worked again.
