I can't recreate the issue, on master or dev branch.

• Did you do some customizations in your theme?
• Also try clearing the assets.
• Did you switch the branch without updating composer dependencies?

I tried again, and I did the next steps:

1. I switch to the latest develop branch on humhub and to the latest(master) on the gallery module
2. I have done all these steps: admin/troubleshooting/#clear-cache
3. But did not update the dependencies. (then I tried again cd into the humhub folder run the composer install, php yii cache/flush-all and removed the assets again. but it persists (with chrome cache disabled in the network tab )

Actual result: 'the loader(spinner) appears on the screen but it does not spin)
Expected result: 'the loader appears and starts spinning'
Additional info:
Please try to add high resolution image like 4k or even 8k may be that is the reason. if I have low-res images I can not event notice the loader, but with high-res it is definitly visible. thank you.
