FAF Client freeze

Happened to me since 1.3.0 I think. FAF Client freezes after a while and remains unresponsive. Can happen basically anytime whether a game is active or not. Error logs keeps pushing this out:

Tracked in https://github.com/FAForever/downlords-faf-client/issues/2169

@Der_Lenz
it has something to do with your mods installed. Maybe remove them ... Documents/My Games/... or in C.//ProgrammData/Faforever/user/...

or maybe that probably has nothing to do with it

https://github.com/FAForever/downlords-faf-client/issues/2169 here is the corresponding ticket. I proposed a fix for it.

On the other hand that might not be the reason for your freeze
