CAD Transforms won't activate on Blender 4.0 alpha

[meikasahara]

The latest Blender 4.0 alpha builds (from May 23 onwards) breka compatibility with the add-on, and as a result it can no longer be used or activated. Upon attempting to activate it, the following error appears in the console:

addon_utils.disable: slcad_transform not disabled

Thank you for reporting.

It seems for Blender 4.0 all strings 3D_UNIFORM_COLOR should be replaced with UNIFORM_COLOR according to the example in the docs - https://docs.blender.org/api/4.0/gpu.html#d-lines-with-single-color

There are probably others incompatible changes in 4.0 as well.

Changing line 402 of the file "gpu_draw.py" to _shader = get_shader('UNIFORM_COLOR') and line 225 of the same file to blf.size(font_id, self._font_size) makes the addon work on current versions of Blender 4.0.0 for the time being.

Can't make it work. It still crashes a lot while using, even with those lines corrected.
