As the problem is browser based a quick solution would be to try an alternative browser. We have found that this has been most successful on Windows environments. You might try switching to Firefox/, Google Chrome or Edge.
This approach has been less successful on Apple devices, probably because of similar security settings across multiple browsers.

Note: After making these changes it is always good advice to close your browser, restart and log back in to Blackboard Learn.
Some users may feel uncomfortable enabling third party cookies and may prefer to add exceptions for specific sites. If that is the case please add api.turnitin.com / api.turnitinuk.com to the sites that are Allowed to use Third Party Cookies.
Enabling Javascript
Some browser settings can block Javascript, so it’s worth checking these settings too.
In Safari, select Safari > Preferences > Security > Web content > Enable JavaScript
In Firefox, select File > Preferences > Privacy & Security. If Strict is enabled, please change this to Standard, or Custom.
In Microsoft Edge, select Microsoft Edge > Preferences > Cookies and Site permissions > JavaScript > Allowed (recommended)
In Google Chrome, select Settings (you can open the Settings page by clicking the icon with three stacked horizontal lines in your browser's menu bar) > Privacy & Security > Site Settings > Content > JavaScript > Please ensure that the option Sites can use JavaScript (recommended) is enabled.
Again if you prefer to use exceptions , please add api.turnitin.com / api.turnitinuk.com to the sites that are Allowed to use JavaScript / 3rd Party Cookies.
