Crash and Error Code 5 during online experiment

Description of the problem:
When running the study online, some users reported a crash with the error code 5. I have been able to recreate this error once, using an iMac and Google Chrome. Interestingly, this error was shown not only on the experiment tab, but also occurred on the Pavlovia dashboard that was open in another tab. Other tabs were not affected.
Is this a known issue?

Thanks!

Not a solution, but more information about the issue
