这个解决方法来自于尼尔森的更新日志：
原文:
Edit for Econ Ticket Failure:
Valve have confirmed they're working on fixing it for the next Steam update, however there isn't a solid release date for that yet. In the meantime a temporary workaround is to dequip your skins and cosmetics.
意思就是说：Valve已经确认了这个经济标签验证失败的问题，将会在下一次Steam更新时修复。
目前尼尔森给出的解决方法是：卸下你所有角色的所有饰品+枪械皮肤
