System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Radeon (TM) RX 480 Graphics ATI Technologies Inc. 4.5.14739 Core Profile Context 21.6.1 27.20.22001.14011

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-06-23 22:10, hash: f7fbb518c8

Short description of error
Using the cloth filter brush with collisions enabled on both the deforming object and the non-deforming object causes Blender to crash.

Exact steps for others to reproduce the error

Open the attached .blend file with a minimal scene where this error can be observed. Everything has been already set up.
With the pre-selected Cloth Filter brush set to Gravity and both Use Collisions and Use Face Sets enabled, LMB on the "Skirt" mesh, and start dragging to the left of the screen, causing the "Skirt" mesh to start flying upwards.
After a brief while, release LMB and repeat the above operation by dragging to the right. Note how the direction of the cloth filter brush was not reversed this time.
Almost as soon as this new sculpting operation is initiated, typically Blender crashes. Occasionally it might take a few more attempts.

Additional notes
If extensive changes are performed to the "Collisions" mesh, the bug will not be able to be reproduced anymore.

I can confirm this on the 3.0.0 alpha.

I am also crashing in the release build of 2.93.1

AddressSanitizer error in 3.0.0:

This issue exists in 3.0.1 too, and extensive changes to meshes doesn't work for preventing.
