I have checked for multithreading and other related issues, but I didn’t find any obvious problems with sub-threads running webview. I have also inspected the interfaces for native pages and webview JS interactions, and the tests seem to be fine. I have checked other block callbacks as well, but I didn’t find any obvious problems
fix the crash，please，help me.i cant find userfull way dealwith this bug
