WispLogic - Collection was modified

### Description

Hi team, we have several crashes in our telemetry (UiPath Studio) related to WispLogic - Collection was modified; enumeration operation may not execute, and wanted to check if this is know / if you have seen this before. Googling for "WispLogic" + "Collection was modified" only returns a bug report on our forum.

Over the past 7 days we've seen this exception 790 times across our user base.

There's a couple of different stack traces associated, but in the same area:

```
