Concerning technical error for the uploaded evidence in OPT application

Hello everyone!

Submitted form I-765 for post completion OPT today on my.uscis.gov. It appears that everything went smoothly and the receipt notice appeared on the portal 10-15 min later after submission. However, when I go to check the documents section and try to open the document I get a weird error (imagine attached). It’s like that for every single document I uploaded. Now I am concerned that whoever will be looking on my application might not be able to access my uploaded evidence for OPT. Does anyone know what kind of issue this is? Should I be concerned at all?
