Assertion `end - begin == length' failed about untrunc HOT 1 OPEN

The failure is due to stack overflow or arithmetic length overflow.
You should do this or refer to the intelligent prompts given to you by VS2022:
atom.cpp 470：if (length >= static_cast(1L) << 32) {
atom.cpp 596：if (length >= static_cast(1L) << 32) {
atom.cpp 645：char* buff = new char[1 << 20];
atom.cpp 650：int64_t toread = static_cast<int64_t>(1) << 20;
atom.cpp 660：delete[] buff;
And other places (probably one to two more)

from untrunc.
