My Blender keeps crashing at random intervals whenever I am in a project using two specific rigs I put together. Most of the time it's completely fine to use them, but other times it suddenly begins crashing again and again, and I can't find a pattern that causes this. My drivers are up to date.
My theory is that it is spamming the Action constraint for some reason, causing it to use too much memory and shutting down.
I do not know how to add a .txt file to this question, but here are some excerpts from the debug log:
WARN (bke.anim_sys): C:\Users\blender\git\blender-v340\blender.git\source\blender\blenkernel\intern\anim_sys.c:3541 animsys_calculate_nla: NLA Eval: Stopgap for active action on NLA Stack - no strips case
There's 3 of these, not sure if relevant.

This one is repeated once more, with the exact same thing written, followed by: Detected 2 dependency cycles
I see that there's a dependency cycle here, but it should be on all the rigs I made and it's only with these two the problems arrive. Then this keeps getting spammed, etc., etc. Most of the debug file is this:
do Action Constraint Action - Ob CameraShakify.v2_Camera.011_0 Pchan (null)
do Action Constraint Action - Ob CameraShakify.v2_Camera.012_0 Pchan (null)

do Action Constraint Action-EyeWide - Ob Rig Chase.001 Pchan CTRL-TWEAK-EYE-LOW03.L
do Action Constraint Action-EyebrowLower - Ob Rig Cano.001 Pchan TGT-EYEBROW04.L
Even with a dependency cycle for the jaw bone, that doesn't explain why it is spamming the action for eyebrows and eyelids. Why is it happening? How do I fix it?
When it crashes it says this:
Error : EXCEPTION_ACCESS_VIOLATION
Address : 0x00007FF6915BADEC
Module : blender.exe
Thread : 00005340
do Action Constraint Action-EyebrowRaise - Ob Rig Chase.001 Pchan TGT-EYEBROW04.L
do Action Constraint Action-EyebrowLower - Ob Rig Chase.001 Pchan TGT-EYEBROW04.L
do Action Constraint Action-EyebrowRaise - Ob Rig Chase.001 Pchan TGT-EYEBROW01.R
And it repeats the entire Constraint Action thing once more for good measure.
It also mentions NLA Eval: Stopgap for active action on NLA Stack - no strips case some more times. What is that?
I see the Shakify add-on appearing in the debug output from time to time. Could it be part of the problem?
Do you think the dependency cycle could be the problem? The mouth bones are constrained to bones parented to the jaw bone so I can toggle them following or not following the jaw.
