Kinda crashed UiPath due to cpu usage and now the entirety of the activities to sequences are gone, reinstalling did not seem to help and I keep retrieving the error above on startup for every different process.

This is what I meant by “gone”.

Any ideas how I can restore the ability to view and manipulate the activities?
I tried debugging it blindly and the codes still seem to work, so its just the view thats the problem. Any pointers are appreciated :slight_smile: !

Also I’m using an old version 2020.10.6 Community License, cant install the newer ones as im using an ancient work laptop at 32bits

Not sure if it will fix this problem or not, however try the following:

1- Update MS Office if possible, the first screenshot complains about excel… too smal to read :slightly_smiling_face:
2- Re-install Dot Net Framework.

Let us know if it works for you… it’s a bummer…

Best of luck!!!

Hello @lmoham

I am facing the exact same error that you have and i now cant event see my workflow created.

Running via admin access is not feasible within my organisation.

Did you manage to resolve this?

It is an out of support version, I would suggest to upgrade to a latest version to avoid any issues. Have you tried using the suggestions I have made in my previous comments.
