Invalid SVG error when editing cards

Prerequisite checklist

• [ x] In case of a bug: Have you tried restarting Anki?
• [ x] Are you running the latest version of the add-on. Have you redownloaded the add-on from AnkiWeb to make sure?
• [ x] Did you check the add-on documentation (e.g. AnkiWeb description, Wiki if it exists) for known issues?
• [ x] Did you perform a cursory search through the existing issue reports?

What is the problem/feature you would like to see fixed/implemented?

I cannot open any IO cards I make after I create them. When I try to edit them, I get this error message: https://imgur.com/NqYXwtV

How can we reproduce the problem?

It was the weirdest thing, but all I did was install the most recent Anki update and I started running into this problem. Before that, it worked flawlessly. The only other thing I can think of that changed is that I did start utilizing the multiple profiles feature on Anki that I had not used before, but I cannot imagine how that would only affect this add on.

1. [First step]
2. [Second step]
3. [and so on...]

**Expected behavior: to edit cards/ add boxes and remove them, resize them etc.

**Actual behavior: Image cannot be reopened in the add on.

**Reproducible?: Yes, every time.

Hi. Sorry to hear about your issue. Would you mind sending me an apkg export of some of the affected cards, so that I can take a closer look? You can either attach it here or send it to me via ankiglutanimate(at)gmail.com

Hej glutanimate, i have the exact same problem, can't edit the cards after creation. (macOs 10.13.6)

I can edit them on a windows machine, but the text in the fields gets screwed up.

I attached some cards.

hi glutaminate, I've been running into the same issues. I am currently on Anki Version 2.1.22 Windows 10 64-bit, and I'm running the latest version of your image occlusion add-on.

I've only noticed this for around a week, but I can't say for certain if it's been going on much longer than that.

However I can edit them on my Mac (Anki version 2.1.23) without much issue.

I've attached some cards here:
