White Screen (of Death) on Mautic Builder

[wayneoutthere]

Describe the bug

I open the mautic email builder and I get an unresponsive white screen in the builder area (menu stays visible) but server stops responding and cannot close window. The only way to exit this screen is a control f5 browser refresh

Context

• Hardware: Digital ocean debian droplet wtih 2GB of ram

• YunoHost version: 11.0.10.2 (stable)

• I have access to my server: *Through SSH | through the webadmin |

• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: *no

• Using, or trying to install package version/branch: https://github.com/YunoHost-Apps/mautic_ynh/tree/testing

Steps to reproduce

1. log in with admin mautic account
2. in left pane go to 'channels'
3. to go 'emails'
4. create new email
5. select 'new segment email'
6. click the 'builder' option to begin building a new email with builder components. Tools load, white page to build on loads, but nothing can be done on page and even builder cannot be closed with 'close builder' button

I also tried the preview button which opens up a second white screen of death, note.

Also note that in the mautic permissions under system info / folder files permissions, everything is showing as 'writable' so that appears good.

Expected behavior

I expected to be able to build an email with the mautic email builder

Logs

There are no logs from Yunohost that appear to be relevant to this error. The only logs from Mautic are as follows which also do not appear relevant but I'll paste them anyways: paste of all mautic logs

Let me know if I can be of any assistance in testing new changes. I may have to install this another way so this next week is 'prime time' for me to test if that happens to work out.
