Profile sketch (Design library) & Bug issues/Crashes

Hi guys I have a few issues I need help with.

I'm having a problem inserting a profile from a sketch I created. The idea was to have a profile readily drawn so I can drop it into different parts (in context assembly modelling). When I try to drag the sketch into a part I get this error.

The second issue is when I am trying to apply textures, materials or appearances. My dialogue box seems to have disappeared.

There's another machine in the office that crashes as soon as a material is applied then you try to edit it.

Lastly I found that these random bugs have started to appear since our subscription expired.

Read into that how you wish.... I have uninstalled the software, updated drivers and graphics card drivers are fine. Rx has reported no errors. I can't update further than SP3 as my update had expired however the other machine is on SP4. This isn't a rant but I find it hard to believe that the hardware I have cannot run the software properly.

Has anyone come across these issues?

Regards
