cmssw: G4Exception in Run3Winter22 MC samples

Dear all, we’ve been observing a G4-related exception in the GS step for the creation of samples for Tracking POG studies within the Run3Winter22 MC campaign in CMSSW_12_2_1. This has prevented the completion of about 1/3 of the needed statistics (see PmP))

The exception is:

-------- EEEE -------- G4Exception-END --------- EEEE -------

Fatal Exception (Exit code: 8016)
An exception of category 'EventCorruption' occurred while

Likely geometry overlap - else navigation problem !
Track *abandoned* due to excessive number of Zero steps. Event aborted.
