Hi,
I have MacBook Pro (15-inch, 2017)
3,1 GHz Quad-Core Intel Core i7
Radeon Pro 560
When plug it into external monitor through thunderbolt it crashes. The fans not working anymore and ther is no keyboard or trackapd. I can only turn off via power button long press.
The problem was not been before 10.5.5 update.
Regards.

MacBook Pro 15″, macOS 10.15
Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
2. Test check if "automatic graphics switching" resolves your issue.

Please can you run this in terminal "system_profiler SPDisplaysDataType" and post the output.
It should give us the details of the GPU & display.
Did you have an issue with ext display when the automatic graphic switching was off?

Since you have already mentioned previously it worked fine before the update.
First step to check make sure if reinstall could fix. Unless it is a Hardware issue.
Please check if the issue persists with the power adapter connected?
Please check with different ports and different connecting adapter?
In safe mode everything works fine. If I turn off automatic graphics switching in about this mac window, there is no graphics section. Apple diagnostics test gets no error at all. Green check mark.
If I connect external display, the window server crashes. Several minutes later the macbook goest to login screen.
Did you try re-installing macOS?
Not now. I have to work, then i think in the evening i will try. What do you think: it is enough just reinstall or i have to do a clean install?
I tried every port and with power and without power adapter. Its crashing. I will try reinstall.
When I arrived at home everíthing worked well... On next monday I can test again the monitor at my workplace. Maybe the cable is wrong...
