Can be a couple of things to be honest & hard for anyone over the forums to diagnose & resolve over the internet.

Could possibly be:

- Gear Selector Fork
- Clutch
- Clutch master cylinder or Slave Cylinder
- Or an actual Gearbox issue

Best bet is to have a reputable workshop check it out when they all reopen next week.
