KERNEL_MODE_HEAP_CORRUPTION (13a) was triggered by vlflt.sys (Bitdefender) as it seems. And another dump shows MEMORY_MANAGEMENT (1a), which could be related!
Rich (BB code):
MODULE_NAME: vlflt
IMAGE_NAME: vlflt.sys
STACK_COMMAND: .thread ; .cxr ; kb
BUCKET_ID_FUNC_OFFSET: 13e496
FAILURE_BUCKET_ID: 0x139_1d_INVALID_BALANCED_TREE_vlflt!unknown_function
@xilolee can you tell us more about this, dump files are not my area to analyse! Thanks!
Hey good job!
I already knew that it was bitdefender that was blocking the bsodcollectionapp, but I didn't have the heart to have caliopus uninstall it.

KERNEL_MODE_HEAP_CORRUPTION
The kernel mode heap manager has detected corruption in a heap.
Type of corruption detected
hex 0x12 (=decimal 18, the first parameter):
The heap detected invalid internal state during the current operation. This is usually the result of a
buffer overflow.

KERNEL_SECURITY_CHECK_FAILURE
A kernel component has corrupted a critical data structure.
The corruption could potentially allow a malicious user to gain control of this machine.
Decimal 29 on microsoft.com (0x139 explanation) =
hex 0x1d (the first parameter):
an RTL_BALANCED_NODE RBTree entry has been corrupted.
