System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2060 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 527.56

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2023-01-14 21:18, hash: cc332264ae
Worked: 3.2.2, haven't tried any other version though. maybe it's only 3.5.0 that has it.

Caused by 3b761901b6

Short description of error
a sudden crash happens, almost as if you pressed the X.

Exact steps for others to reproduce the error
you can do this on any file in 3.5.0 alpha. go in edit mode on an object, enable X, Y or Z mirroring. move, rotate or scale the object and cancel it. it will then crash blender. hehehehaw.

Crash occurs below - the val field on the transform data struct is uninitialized:

blender.exe!transdata_restore_basic(TransDataBasic * td_basic) Line 815	C
blender.exe!restoreTransObjects(TransInfo * t) Line 869	C
blender.exe!transformEnd(bContext * C, TransInfo * t) Line 2039	C
blender.exe!transform_modal(bContext * C, wmOperator * op, const wmEvent * event) Line 434	C
blender.exe!wm_handler_operator_call(bContext * C, ListBase * handlers, wmEventHandler * handler_base, wmEvent * event, PointerRNA * properties, const char * kmi_idname) Line 2406	C++
