issue with datamixer

[oword]

im not too sure whats going on with the datamixer I've used it before and it worked perfectly fine but I tried to use it today after reinstalling and it gets to about 43% where it used to just freeze and then after a bit mosh but now it gets to 43% and just sends me back and unfreezes instantly there is only 1 clip on the supposed datamixed clip but theres nothing in it just 1 frame of the previous clip

Same issue. Datamix script works fine on two 16:9 clips of different resolutions and frame rates, but doesn't work on two 1080p and 30fps portrait clips shot on a Galaxy S22. Rendered clip has no datamixing or other visual differences; just looks like a normal jump cut. Render window closed at around 44-48% render progress in both cases. Datamixing Galaxy S22 clips shot in landscape mode made no difference.
