Short description of error
When executing transform.resize or transform.translate with context.temp_override(area=uv_area) Blender crashes. This happens when the area.ui_type is UV, with VIEW_3D is works fine.

Error   : EXCEPTION_ACCESS_VIOLATION
Address : 0x00007FF72DEF3C80
Module  : blender.exe
Thread  : 000009dc

the complete crash file is attached

Exact steps for others to reproduce the error

create a new Text and paste the below code into the text (the attached file issue.blend can also be used)

import bpy 
context = bpy.context
area = context.area
area.ui_type = "UV"
with context.temp_override(area=area):
    bpy.ops.transform.resize(value=(0.5, 0.5, 0.5), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=False, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False, snap=False, snap_elements={'INCREMENT'}, use_snap_project=False, snap_target='CLOSEST', use_snap_self=True, use_snap_edit=True, use_snap_nonedit=True, use_snap_selectable=False)
    bpy.ops.transform.translate(value=(0.25, -0.25, 0), orient_axis_ortho='X', orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=False, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False, snap=False, snap_elements={'INCREMENT'}, use_snap_project=False, snap_target='CLOSEST', use_snap_self=True, use_snap_edit=True, use_snap_nonedit=True, use_snap_selectable=False)

run this text, Blender will now crash

Note: not using temp_override() and executing these operators in the current context with the ui_type set to UV works fine. Like this:

import bpy 
context = bpy.context
area = context.area
area.ui_type = "UV"
bpy.ops.transform.resize(value=(0.5, 0.5, 0.5), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=False, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False, snap=False, snap_elements={'INCREMENT'}, use_snap_project=False, snap_target='CLOSEST', use_snap_self=True, use_snap_edit=True, use_snap_nonedit=True, use_snap_selectable=False)
bpy.ops.transform.translate(value=(0.25, -0.25, 0), orient_axis_ortho='X', orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=False, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False, snap=False, snap_elements={'INCREMENT'}, use_snap_project=False, snap_target='CLOSEST', use_snap_self=True, use_snap_edit=True, use_snap_nonedit=True, use_snap_selectable=False)

Thanks for the report. I can confirm the crash.
But unable to replicate when I pass remaining parameters to temp_override (i.e. window, region)

Ok, so apparently it does not crash when the region is specified. In other cases, it does.
So if the area is passed, the region is required (at least for ui_type='UV').
e.g., temp_override(area=uv_area, window=context.window, screen=context.screen) does crash
but temp_override(area=uv_area, region=area.regions[0]) does not crash (same for temp_override(area=uv_area, region=area.regions[0], window=context.window, screen=context.screen))

From https://docs.blender.org/api/4.0/bpy.types.Context.html#bpy.types.Context.temp_override

When overriding window, area and regions: the arguments must be consistent, so any region argument that’s passed in must be contained by the current area or the area passed in. The same goes for the area needing to be contained in the current window.

Guess this could be improved upon (maybe @ideasman42 can come up with a better wording), but it basically tries to tell you area & region must "fit".
