A user reported that when calling SetText on a text widget in a widget blueprint's PreConstruct causes an editor hang when you put a breakpoint on SetText and attempt to save the asset.
The issue is 100% reproducable in 5.3.2 and 5.4.0 Preview 1. In 5.3.2 it causes an editor hang. On 5.4.0 P1 it triggers a native break via UE_DEBUG_BREAK() in FSlateApplication::EnterDebuggingMode(). In both cases it should enter blueprint debugging mode instead.
The following messages are logged:
[2024.04.17-10.50.01:719][346]LogBlueprintDebug: Warning: Hit breakpoint on node 'CallFunc_SetText', from offset 10[2024.04.17-10.50.01:719][346]LogBlueprintDebug: Script call stack: Function /Game/WBP_Repro.WBP_Repro_C:PreConstruct Function /Game/WBP_Repro.WBP_Repro_C:ExecuteUbergraph_WBP_Repro
