For Collis & Eggers (2022 https://doi.org/10.1371/journal.pone.0272416), Table 6 seems to have the relevant results, albeit perhaps with a subtly different standardization of effect sizes, no? There is an estimated effect on life satisfaction of -0.020 SDs and on mental well-being of -0.018 SDs.
Regression models in Table 6 provide correlations too minuscule (|r| <= 0.02) to explain d = -0.138.

BTW, one trouble with the regression in Table 6 is that authors include having a job in controls but do not include course workload. Assuming we allow controls beyond demographics, why include job but not course workload? Note that Treatment had a significantly higher course workload, which may have led to higher stress.

I do mention Table 6 in my critique:
