Welcome to the folding support forum.
The WU highlighted in your screenshot has already uploaded successfully:
Hi Alq_Veers (team 236077), Your WU (P18202 R5346 C1 G12) was added to the stats database on Invalid Date for 67770 points of credit.
So has another WU listed:
Hi Alq_Veers (team 236077), Your WU (P18202 R12631 C1 G15) was added to the stats database on Invalid Date for 67770 points of credit.
It appears the acknowledgment packets that a WU upload has successfully completed are not getting back to your system. This can be local to your system, or happen because the packets were dropped anywhere between the server and your system. Load settings by some routers may do this, they consider HTTP ACK packets as less important to transfer.
Locally people have reported that resetting their router fixed this. Other possibilities include anti-virus/anti-malware that has recently updated and changed settings, MS Defender has been known to do this. If you were in Europe I would ask if you were using a Fritz!Box as your router, their default settings can cause the same problem.
If the problem is not local to your system or your network connection it is harder to diagnose and get things working normally again.
You can check the upload status of WUs by using this app -
https://apps.foldingathome.org/. You can either enter the PRCG numbers directly into the fields or copy and paste from the log into the first line. With the client paused, then delete the folders from the "work" directory in the F@h data directory numbered the same as the WUnn shown in the log. Unpaused the client will stop trying to send those, that can make it more likely for the remaining WUs to upload.
