Suddenly constraints dont work on assemblies

[labrakis6JLPE]

Hello all!
I have been buliding an assemby for the last three days.
I saved it last night. Today i opened the filed in order to continue. I added a new part and begun adding constraints as usual. The "the asse,bly cannot be solved" error appeared.
At first i thought it was a conflicting constraint and spent sometime trying to figure where it was.
As i continued i realised that no constraint would work anymore. No part would be moved, 
I googled, i found the common "defer update" box, it was not ticked i ticked and now i can hear the usual sound but part dont move. The preview glasses are also greyed out.
I tried to make a new assembly but no constraint is accepted. 
Any ideas?

Thank you!

HI!

Try Inventor reset tool.

which is where??

Well! Problem solved! I discovered a constraint in another part (totally irrelevant) with the new ones i was trying ti aply that was blocking ...the whole universe. I deleted it and everything is back to normal. 
For the history of it, the defer update button i found on google did nothing at all (i have no idea what it is about) and when it is pressed the preview button goes off.

Thanks anyway!

The Defer constrain only aply the constrain when you click UPDATE, doesn't apply with OK or make the preview, and that's why the glasses turn to grey.... the glasses are the constrain preview.

BTW, for future needs, the inventor reset tool is here:

Hi! If you are on 2023.0 (RTM), please install 2023.0.1 update. There is a known issue very similar to yours got fixed in the update.

Many thanks!

Hi! Then please share the files that you are working on. The behavior sounds like preexisting failed constraints or adaptive related.

Many thanks!
