Another serious problem im facing since upgrading to the latest engine version 4.12.5 .
Once the above crash occurs , it happens everytime whenever i try to open anything ikinema related ( ik rig , animation blueprint etc ) until i restart the pc itself . In order to avoid the above problem i had to delete my animation blueprint itself . So far i deleted like 3 times and it was frustrating . fortunately those animation blueprints were tests only . Im hoping for a fix soon since this crash seems to be related to the latest 4.12.5 .
