unexpected error

This is on Alteryx Designer 2020.2. 

The errors began immediately after upgrading to this version.

It is not on my local machine but on a server I remote into. 

It is not perfectly clear when this happens but I have the general idea:

I pull a workflow down from our local gallery > I expand a collapsed container. BANG. Error. Typically, after I hit "ok" on the error, the same error will pop back up 2-3 more times, generating that many more error logs.

After the error windows go away, the tool container goes back to being collapsed. It will not stay open... except for one out of 10 times I've been through this process... it did stay open and I tried going about my work until it stopped working again (meaning that I had to close the workflow and when I restarted it gave me errors again). 

 

I get one of two types of errors:

1) Message: Collection was modified; enumeration operation may not execute.

2) Message: Cannot access a disposed object.

It's unclear when each error occurs, though the second is almost always the one I get.

 

This is among many other frustrations with Alteryx. Please advise. Do I need to submit a ticket?

Yes, for this kind of problem with such technical depth I'd recommend going straight to alteryx support, just send an email to support@alteryx.com, and to save you some time you can just reference this community post!

 

Appreciate this is a week after your post so you are likely to already have done this!
