Unable to upload Photos

Hello,
I have a similar if not the same issiu as this topic: https://line-of-action.com/forums/topic/unable-to-upload-photos-for-a-photo-bundle
I've also tested out a variation of file sizes, different images etc. Tried to upload single photos as well as bulk upload but nothing worked. I've tried it multiple times over the last few weeks.

I always get following message:
"Something went wrong
Uh oh, it looks like the site is experiencing some sort of problem. If you continue to receive this error for more than a few minutes, you are strongly encouraged to send a bug report."

Here is an example of a photo I'm trying to upload (One Drive link):

I also wrote an e-mail last week or so. I'm unsure if you just haven't gotten to it yet or if I accedently had a typo in my e-mail adress.
I'm using the brave browser in case that's impotant to know.
