For me the game kept crashing because f*cking OneDrive moved the save files to cloud and deleted them in my local, save files are present in My Documents -> Phonexies folder, the game started properly when I had synced the save files to my PC and make sure to keep the status as 'Always Keep on this device' by right clicking on the folder to keep the future saves in local and not delete them even if they are synced to the cloud. See if this is your issue and the suggestion helps.
