i... wish i could provide any info to this, but not even the logs will show anything. due to the fact that it freezes before the drainer appears on screen i assume it's a clientside problem with how the model is set up. will update if i find the incompatible mod

stability field gen is fine. but i've had similar issues with the diffuser, impetus matrix and the vis regenerator, so probably sth to do with the way you've implemented the rotating bits. The matrix kinda surprised me tbh, but on second thought it makes sense. meanwhile all standard thaumcraft blocks (including the regular runic matrix) work perfectly fine

also, it still appears to freeze even after removing renderLib and co. this might be a deeper issue with more mods involved. the easiest band-aid fix i could think of rn would be to make another variant of these blocks that function the same but without the animations

UPDATE: got a legitimate crash report. it's renderLib. this mod is required for nothirium which is kinda essential for basically being a sodium equivalent for 1.12.2 so it'd be appreciated if there was a fix sometime soon

I'll look into it. Do other animated blocks have the same issue? Examples: impetus matrix, stability field generator, impetus diffuser

UPDATE: for some reason it works now. i did remove a few mods, but more or less coincidentally.
