"System.OutOfMemoryException"/Desktop keeps crashing

Hi v-piga-msft, 

I've attached both the errors from the log file below. I couldn't upload more due to the message character limit and I can't see any way to attach a file. 

I'd appreciate it a lot if you could take a look, and let me know if you need any other information 

thanks :)
