yup having the same problem. after update all of a sudden i cant even boot, have to get into safe mod and uninstall.
i have found that occasionally i have been able to re install (tried many versions) 1.2.51 and it worked until i shot down my pc then back to the same freezing on start up.
i tried to go in to %appdata% and turn TT off from start up but still freezes. have uninstalled and re installed all the windows c++ drivers. which after i install TTRGB and have to uninstall i notice it corrupts my 2017 c++ and have to re instal.
I have not added any new software, been running it with success for 3 months then one day after coming out of sleep i have had this issue...
Gaming rig is about 8 months old, run MSI and Rivia Tuner on start up and Rocket Docket, other then that just a few normal Windows 10 programs.
