So, today the enviolo heavy duty hub decided to catastrophically fail while pulling my kids (kids + trailer about 50kg) on a 22% incline. Its life was a bit under 7000km. Since the part is quiet expensive ( around 500 Euro) and I'm not particularly happy with this system, I'm thinking of switching.
All my other bikes have shimano drivetrains.
I'm wondering if this switch is just a matter of getting a new wheel with a micro spline freehub, cassette, the shifters and the proper crankset? Thanks.

Yes, a new hub (plus spokes and build labor) or a new wheel, cassette, derailleur, chain, crank (or at least chainring) and shifter. If it’s an integrated brake/shift lever you’ll need a new brake lever too. With labor to have a shop make this switch, I wouldn’t expect to save a lot off the 500 price tag.
Switching to another drivetrain is usually not that trivial. Lots of unknowns to deal with. First question is, for your frame have a derailleur hanger? If not I would not recommend a switch. You would have to look at welding a hanger or something similar, and then we haven’t even looked at suitable drivetrains for your use case, chain lines cranks etc.
Hauling up probably around 150kg up a 22% incline (probably electric or with hulk power) is quite the torque. Not many internal geared hubs would like that much. Probably rohloff would be best, but that is even more expensive.
Ah yes, enviolo, the hub that “lasts forever”, is not serviceable but also breaks once a year. I heard many stories of this POS breaking.
Also, does your bike have an electric motor?
You need a new wheel with the right hub (either HG or microspline, depending if you go 11 or 12 speed shimano), or a integrated gear hub from shimano.
You need a derrailleur hanger for your frame, if you don’t already have one.
New shifter, derraileur, chain. It may be possible to just swap the chainring on your existing crankset.

Alternatively you could get Alfine 8 or 11 speed wheel and keep a belt or convert to a chain.
A derailleur drivetrain and an enviolo drivetrain usually use different style dropouts. An enviolo hub with a solid axle (which is most of them) uses a 135mm axle standard the modular one is 148mm but very rarely used. 12spd shimano hubs are usually either 142mm or 148mm and thru axle, so not really a straight swap most of the time. If your frame is with swappable drop outs you can probably make it work. If it’s not it’s an uphill battle tbh, take some pics of how the wheel is mounted in the frame and i can tell you with a high degree of certainty wether it’s possible or not.
