Gcam not working on my Custom GSI-installed phone

Question

I installed a custom gsi on my phone, Infinix Hot 20s (X6827), which is the unofficial version of Evolution X GSI. My phone only supports FULL in Camera2API. And the only problem is there's no RAW support. Is that the problem?

When I try to run GCAM, it crashes and I copied the error code:

Can't I really use GCAM?

Tried LMC 8.4 gives the same error. Tried on other GSIs, also not working.
