error: expected a class name after '~' to name a destructor

[NadimintiSaiSirisha]

I am using Qt version 5.12.12.

When trying to run the code in Windows 11, I am facing the following error in GUI/drs4scriptdlg.cpp

DDRS4PALS-master\DDRS4PALS-master\GUI\drs4scriptdlg.cpp:883: error: expected a class name after '~' to name a destructor

It points to the code snippet from line 883:

QString compl = completion;
compl.remove("int_value_of_maximum_1024").remove(""name_of_file"").remove("int_value_in_mV");
compl.remove("int_cell").remove("int_number_of_points").remove("double_value_in%_");
compl.remove("bool_using_linear?").remove("bool_using_cubic?").remove("int_delay_in_nanoseconds").remove("double_value_in_picoseconds");
compl.remove("bool_positive?").remove("bool_burst?").remove("int_value").remove("bool_areaFilter?").remove("bool_burstMode?");
compl.remove("bool_automatically?").remove("variant");
compl.remove(" << bool").remove(" << int").remove(" << double").remove(" << string");

Please help to resolve this.

I am attaching the screenshot for reference.
