Routing amp, Tonex and UAFX pedals via switcher/loop pedal - NOISE

I’ve been experimenting with a routing setup that produces noise into the signal that I haven’t been able to solve.
I tried a Lehle D.loop SGOS in which I routed 3 loops: one containing a Tonex pedal, one containing a UAFX Lion 68 and one containing a Bogner Ecstasy 101B amp head going into a Suhr Reactive Load. Guitar goes into a compressor and number of drive pedals into the D.Loop, output of the D.Loop goes into an Ox Stomp stereo out into 5 Strymon pedals into my RME Babyface.
I expected Lehle to be top quality and I’ve been in touch with their specialist to resolve this but without a definitive answer to what is causing the noise issue. I also contacted Suhr about their reactive load without a definitive resolution to the problem. The same noise issue happens with the cheap Paramix from GuitarPCB with the Bogner - Suhr RL into one of the loops. With the amp off the noise was still there, only after taking the power cord from the plug did the noise go away. So it must have to do something with the amp IMO.

The noise is produced as soon as the Bogner and Suhr RL are added in a loop. Using only the Bogner and Suhr RL straight into my DAW or the Ox Stomp into the Strymon effects or straight into the DAW without the Strymon effects works without problems. The UA Ox Stomp handles this signal without issues.
I‘ve tested combinations of Bogner/Suhr RL with Tonex in 2 separate loops, same with UAFX Lion 68 and all 3 in separate loops.
The noise produced is not a low hum but more like a higher pitched crackle. It’s almost similar to the noise you get in your DAW when using multiple USB devices where one has to be filtered or the ground has to be removed.

So it seems ground loop related? Before I start buying all sorts of stuff and experimenting I’d like to ask for help if anyone here has experience with this kinda setups and can provide a solution to this problem? Are there devices that can prevent or filter the hum, that can fix the ground loop? For instance, I‘ve owned a Boss ES-8 before but I can’t remember it having options to remove ground loops etc.?

Thanks for your help!
