Hello.

In the last month, Trados has unexpectedly started showing extremly annoying behaviour when trying to open sdlxliff files and creating target files, making my work difficult and time-consuming.
 

1) The "Invoke or BeginInvoke cannot be called on a control until the window handle has been created" appears almost every time I want to open files, which takes extra wasted time and I have to manually open the files.

2) The SDL XLIFF validation error at line 6618 offset 2420538. The key sequence 'xxxxx-xxx-xxxx-xxxx-xxxxx' in 'urn:oasis:names:tc:xliff:document: 1.2:U_tu_segsrc_mid' Keyref fails to refer to some key" [It would really be helpful if this could simply be copied from the error windows instead of manually typing gibberish] (attached image file).

these errors started showing up after I applied the last update with Trados 2017. Any helps is appreciated. Thanks.
