Error running sec2cor in Sentinel 2 toolbox

I am trying to use the sen2cor within the toolbox but I keep getting this message,
“It seems there was an error on execution or the defined tool output error pattern was found.Please consult the SNAP log file.”

Which says,
nap]: Executing tool ‘Sen2Cor 2.11.0’ with command line: ‘C:\Users\boxer.snap\auxdata\Sen2Cor-02.11.00-win64\L2A_Process.bat E:\Dropbox\Arras\Sent2\S2_T43UDT_20220918\S2_T43UDT_MSIL1C_20220918\GRANULE\L1C_T43UDT_A028903_20220918T061158 --resolution 10 --datastrip E:\Dropbox\Arras\Sent2\S2_T43UDT_20220918\S2_T43UDT_MSIL1C_20220918\DATASTRIP --tile E:\Dropbox\Arras\Sent2\S2_T43UDT_20220918 --output_dir E:\Dropbox\Arras\Sent2\S2_T43UDT_20220918 --GIP_L2A C:\Users\boxer.snap\auxdata\Sen2Cor-02.11.00-win64\L2A-GIPP211-custom.xml --GIP_L2A_SC C:\Users\boxer.snap\auxdata\Sen2Cor-02.11.00-win64\L2A_CAL_SC_GIPP211-custom.xml --GIP_L2A_AC C:\Users\boxer.snap\auxdata\Sen2Cor-02.11.00-win64\L2A_CAL_AC_GIPP211-custom.xml --GIP_L2A_PB C:\Users\boxer.snap\auxdata\Sen2Cor-02.11.00-win64\L2A-PB-GIPP211-custom.xml’
