Occasional error

Hi, I’m occasionally getting an error, but much too infrequent to say much about it. Today I copied the message which is this:

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you’ve discovered the add-on that is causing the problem, please report the issue to the add-on author.

Did you have any add-ons enabled when the error appeared?

Please follow the steps on When problems occur - Frequently Asked Questions

Yes I have only two: “Add Table”, and “Image Occlusion Enhanced”.

Thank you but the problem then is that this only happens like 1/50 times… So even if I start in Safe Mode, it’s hard to tell whether it worked for that reason or not. But I’ll try to remember to do it, who knows.
