UI path not responding

Hello,

I have already developed a flow using studio, studio is going to not responding status while creating a condition or trying to copy paste a activity or sequence, I am unable to proceed further as it closes automatically. I have tried it on different machines and the problem is still same. Is this due to flow is large or many number of variables ? because I am using around 70 IF conditions in that particular workflow.

Could you please help us to avoid this issue by any way? as it is causing me work stoppage and I have to move it into production by end of the day today.

Early response is much appreciated. Thanks.

Please find the attachment of the error I am getting every time when trying to make changes in the particular workflow.

Regards,
Raviteja.
