WOke up to see the crash error... it says as follows:
Microsoft Visual C++ Runtime Library
This application has requested te Runtime to terminate it in an unusual way.
Please contact the applications support team for more information.
When i click OK ... opal wallet comes to background and says: Opal-QT .exe has stopped working
Running off outside to have a bite to eat

see ya'll around m8's.
maybe your cpu got overloaded? i had this error last days over night cause i had too many projects and programs open.
usually i don't have any problems with opal qt. but it was only opal qt crashing over night. no problems with staking btcd wallet or any other programs
