Most crashed and issues are more often software conflicts or in amd's case not leaving well enough alone.
I am currently using 4 controllers running 17 fans, 8 feet of rgb, flow aio and hot wired a Akasa rgb m.2 card to it.
I have had no problems since when I first picked them up and had some conflicts but that was my issue not thermaltakes fault.
Now your issues. Crashing and random opening
The random opening is caused by a bug introduced in 1.3.4 and they are working on it.
As for your crashing that is most likely a install issue or software conflict.
Uninstall the ttrgb software and delete the Tt folder at C:\Users\*your username*\AppData\Roaming\Tt
once you have done that you can reinstall 1.3.3 so you don't have the random open bug here https://file.thermaltake.com/file/software/TTRGBPlus_Setup_133_x64.zip
