Error while building solution Arithmetic operation resulted in an overflow - CSC error CS7065: Error building Win32 resources

Got this error while building solution on CI server using VS2019 - 16.7.4

Any idea from where it could come from ? It doesn't happen all the time and only one solution. Can workaround by cleaning completely build working folder
