I'm having a problem right now accessing my desktop wallet. I cant open it, it has an error message

Assertion failed!

Program: C:\pesobit-source-master\pesobit-qt.exe

File:src/kernel.cpp, Line 367

Expression: pindex->pprev || pindex->GetBlockHash() == (!fTestNet ? hash GenesisBlock: hashGenesisBlocktestNet)

and whenever I click retry it says Runtime Error!

this happened after my area had brownout.

what is the solution for this? TIA!
