Hi @Łukasz Czer ,
Welcome to Microsoft Q&A forum.
Though I noticed that you have tried to repair VS, normally, repairing VS should work.
I suggest you try to clean some cache files and repair some corrupted files.
Clean cache and restart VS:
- Go to
C:\Users\[username]\AppData\Local\Microsoft\VisualStudio\17.0_XXXXX
andC:\Users\[username]\AppData\Local\Microsoft\Blend\17.0_XXXXX
, delete/renameComponentModelCache
folder in every 17.0_XXXX folders.
Repair files:
- Use SFC tool to scan and repair missing or corrupted system files.
- Try to update Windows OS.
Besides, please try to run VS/Blend as administrator and see if this works, if it works perhaps it’s related to permission. And if you installed some extensions in VS/Blend, try to disable them in Extensions > Manage Extensions > Installed, and restart VS/Blend.
Best Regards,
Tianyu
