Error on Personal Environment

Hello everyone, for a couple of weeks I have noticed something strange on my Personal Environment on O11. First thing I noticed was on Service Center where I couldn't open the Factory session showing this error soon as I pressed to open that section. 

"The type initializer for 'System.Collections.Generic.EqualityComparer`1' threw an exception."

But as I didn't use it for those weeks, I thought it was some OutSystems issue that was going on and later on was going to be fixed. Today I went to publish on my Personal Environment and I couldn't, I had this error. While Service Center presents the same behaviour.

I checked lifetime and I do have 1GB of space left, so I am really wondering what's going on and if someone had a similar issue and how to fix it. Thank you all in advance.

Hello @Diogo Ferreira,

I think you should open a Support ticket here, as I believe the issue is not on your side.

Hello @Sherif El-Habibi !! 

I thought that was the case but before doing that I wanted to check here if someone had a solution that wasn't opening a Support Ticket!

Thank you for your quick answer!!
