Error: s0: Cannot find sequencer/sequencer.elf

Hello,

After a recent Windows 10 update we are unable to regenerate a Platform Designer system. First errors printed are:

Error: s0: Error during execution of "{C:/intelfpga_lite/19.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally

Same happens with versions 18.1.1 / 19.1.0 / 20.1.1

Is there a patch / workaround?
