Error "Invalid file identifier"

[apw10]

Hello,

I use Matlab 2017b at Windows 7 and I used the logger in the following way

[~, tmp_name] = fileparts(tempname);
General.LogFileName = fullfile(General.OUTDIR,['AnalyzeLog_' tmp_name '.log']);
fprintf(2,[regexprep(General.LogFileName,'\','\\\') '\n']);
Lg =  logging.getLogger('mylogger', 'path', General.LogFileName);
Lg.setLogLevel(logging.logging.ALL);
Lg.setCommandWindowLevel(logging.logging.ALL);

At a certain time point of the function I get the following error message.

Error using fprintf
Invalid file identifier.  Use fopen to generate a valid file identifier.

Error in logging/writeLog (line 173)
        fprintf(self.logfid, logline);

Error in logging/info (line 104)
      self.writeLog(self.INFO, caller_name, message);

Error in dataComb (line 5)

during a simply task
Lg.info(['color ' int2str(kcolor) '_' curr_col]);

Thank you
