It is not possible to install ReactOS - BootCD-0.4.15-DEV-3440-G915569A-X86-GCC-LIN-DBG. (Regression.) (Error unstable ~ 50/50%)

It is not possible to install ReactOS - reactos-bootcd-0.4.15-dev-3440-g915569a-x86-gcc-lin-dbg.iso. (Regression.) (Error unstable ~ 50/50%)

ReactOS is sometimes installed sometimes not. The first part of the installation is going well. The second part of the installation begins, but when the ReactOS installation window should appear, a BSOD occurs.
The regression boundary cannot be determined. The error started appearing after adding a new memory manager. Previously, unsuccessful installations also happened, but rarely.
