Caused by 2ba1cf4b40, 9681708c1c was not enough to fix

Short description of error
When multiple objects are edited at the same time, editing their UVs causes a crash. If not immedietly when clicking an UV set atleast after couple clicks.

Exact steps for others to reproduce the error

Open attached .blend file
Click one object and then Shift+Click the second
Tab to edit mode
In UV editor in vertex mode select a vertex
Press G, it crashes either immediately or after couple moves

Thank you for helping

There was #80561 (Crashing when I alter UVs in multi-mesh editing (using proportional editing)), but apparently the fix was not enough.

At least it asserts for me with the file from the report (checked the meshes, thy are valid afaict)

BLI_assert(BM_elem_flag_test(l, BM_ELEM_TAG) == 0);
