I think this is a regression. I have an older Wine installed in a separate directory (I think it is some 3.18 version) and there installation works.
Can you confirm that a new launcher is not affected to this problem on older Wine version? Screenshot of launcher for comparison is attached. I check this problem on forums and found that older version of WoT launcher is not affected.
Also temporary workaround for new launcher is limit download speed (also recommend do it for upload or disable it). 512KB/s is worked for me. If launcher is still crashes, try set a lower speed.
