Please see the column Max # of concurrent sessions in this matrix. GeForce series has a restriction. https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new#Encoder

Of course, we need to fix the crash bug, but you cannot use multiple sessions unlimitedly even if the bug would be fixed.
