Report saving error and PBIX file automatically deleted from file folder

This issue has continued to haunt me. Its to the point now where I am saving 2 Power BI files every time I make a significant change (PrimaryFile.pbix & PrimaryFileBackup.pbix). I continue to 'save as' and update the backup file and then another 'save as' to get back to the primary file. 

A couple of things that I have done to try and help is increate teh data cache in the Power BI file and with changing the auto recover to every 5 min (Default is 10). Even with that I continue to recieve the following errors. 

1st I get the out of memory error. When clicking ok I get the message from a webpage and clicking ok on that acreen asks if i still want to run the script. Please note that this is not a onetime popup. Even though I click ok on the 1st 2 screens and then no on the final screen I still get about 5-10 rounds of these messages before my power bi file is completly frozen. It's at this point that I have to end the task from task manager.
