It definitely can be frustrating to have things crash. Though it’s hard to say what the issue may be with the amount of context you’ve provided. Could you provide a bit more information about your setup? (Ie. browser and version, system you’re using, background processes, things you’re doing prior to freeze/script, are crashes happening in the editor or preview).
Generally, things seem pretty stable for me. (When I have issues, it’s a result of me using an underpowered computer, many “re-tests” of functionality in preview mode, making a massive change (ie. deleting a large number of elements and associated workflows - but for that give the system time to process).
Here are a few suggestions:
Try switching bowsers and see if the problem persists.
If you have a high number of issues needing fixing, try clearing out any backlog. Then see if the problem persists or also happens on pages where there are no flagged issues.
I’d recommend checking under the hood with your browser. (Any extensions you’re using that might cause issues, etc.)
If issues are happening in Preview, then make sure you’re not trying to load some massive amount of data when the page loads.
