ZWCAD crashes when loading more than two commands (since release 2.2.25)

[gswifort]

I have the following project structure:

.
├── venv/
├── pyrx_onload.py
└── cmds.py

# pyrx_onload.py
from pathlib import Path
import traceback
from pyrx import Ap

BASE_DIR = Path(__file__).parent

def OnPyInitApp():
    try:

        Ap.Application.loadPythonModule(str(BASE_DIR / "cmds.py"))
    except Exception:
        traceback.print_exc()

# cmds.py
from pyrx import command

@command
def doit1():
    print("DOIT1")

@command
def doit2():
    print("DOIT2")

@command
def doit3():
    print("DOIT3")

Everything worked until v2.2.24. Since v2.2.25, it's crashing ZWCAD on several computers in our office. On the others, everything works as before. On the affected computers, everything works if no more than two commands are loaded. If three or more commands are loaded, ZWCAD crashes. It doesn't matter whether all the commands are in one module or one command in three modules—that doesn't work either:

.
├── venv/
├── pyrx_onload.py
├── cmds.py
├── cmds2.py
└── cmds3.py

# pyrx_onload.py
from pathlib import Path
import traceback
from pyrx import Ap

BASE_DIR = Path(__file__).parent


def OnPyInitApp():
    try:

        Ap.Application.loadPythonModule(str(BASE_DIR / "cmds.py"))
        Ap.Application.loadPythonModule(str(BASE_DIR / "cmds2.py"))
        Ap.Application.loadPythonModule(str(BASE_DIR / "cmds3.py"))
    except Exception:
        traceback.print_exc()

# cmds.py
from pyrx import command

@command
def doit1():
    print("DOIT1")

# cmds2.py
from pyrx import command

@command
def doit2():
    print("DOIT2")

# cmds3.py
from pyrx import command

@command
def doit3():
    print("DOIT3")

The biggest problem is that I can't tell what's different about these computers from the others, where everything works.

2.2.25 I enabled AVX2, could cause a crash if the computer is older than 2015, that’s the only thing I see that could cause a crash on some computers and not others, I can turn roll it back AVX

If it's not too much trouble, please do it. If you build it, I'll test it.

[CEXT-Dan]

Sure, no problem
BTW, I tried the first pattern with cad_pyrx-2.2.28 on ZWCAD 2026, there were no issues

It seems to be working :)
Thank you very much

[gswifort]

are you planning a new release soon?

[CEXT-Dan]

I'll make a release for this issue tomorrow afternoon
