Resit in dissertation leading to issues in PSW

Hello, I’m looking for guidance on a situation that I encountered.
I’m an international student pursuing my Masters degree in the UK. It started in January 2024 and was supposed to finish in Jan 25 but I failed in my dissertation and got a resit.
The submission date for resit is 7th April 2025 and my current student visa is only valid till 18th May 2025. Normally they release provisional marks in 2-3 weeks which is before my visa expires but they have a portal called Solar where the marks are uploaded after the university board has approved them which takes around 2 months and it is after my visa expires.
I tried to connect to the visa team and they told me it is impossible for them to release marks early even though the student has to go back to the country and it won’t be possible for the student to apply for PSW.
I connected with some previous students and one of them faced similar issue and he applied for some 4 month extension and then applied for PSW but on my Coventry University’s student portal it says extension will only be allowed if the students needs to attend classes or attendance is required which is not required in my case. We have resit without attendance.
Can someone please help me on this matter as I’ve got education debt and If I don’t get Psw i’ll face a lot of financial stress.
